What you have to do, is ADD the new record in with the existing record. Hit EDIT to the right of the existing record, then hit the + to add a new record to it.
See, all of the records are grouped by the @ / subdomain. If you're trying to add a new @ TXT record and you already have another @ TXT record, you're adding it in the wrong place if you try to use the top input field area. In all honestly, this is a horrible UX choice on the Google Domain teams part. They should have it automatically merge in a new record with what is already there instead of making you hit Edit -> + THEN add the new record...
I say all of that and while the UX may seem like a bad design up-front, it really isn't all that bad "once you get used to it". The problem is that 99% of all other registrars use a single line to add a new record just like Google Domains. The difference is that when you add the line on other registrars, the line is added as a completely new line so it doesn't care if the Name is already used. Google Domains on the other hand, only reserves this blank input form for brand new DNS records that haven't been associated because all similar types and names are grouped together. Since almost all of the registrars use a blank input for adding all records, people come over to Google Domains and expect it to work the same way, then can't figure out why they're getting Record already in use errors for simple DNS additions. If you're adding different CNAMES with the main input form, you shouldn't ever see the error unless it does actually exist. On Google Domains for MX records, TXT records SRV records etc where there can be multiple records for the same type and name however, you can only use the input form on the very first creation of the record type to get it going.
The way Google does it is super easy and doesn't take that long when you get used to it, but if you're new to Google Domains or coming back after some time away, that wonderful ol' error Record already in use can be a pain to troubleshoot because it doesn't follow the same UX pattern of any other registrars.

Really appreciate you posting this...by far the only helpful resource out there on this issue.
Thank you. This error also occurs if you try to save two new "A' records at once on separate lines, even if an "A" revised does not currently exist. You have to add one and then add to existing for the second.
This comment here fixed my problem. Thank you for a simplified alternative answer!
This is spot on. They could fix it with a single line of text that points you at the correct thing to do. Thank you for posting probably saved me 15 minutes ...
synthetic records doesnt exist anymore
guess google domains got rid of synthetic records cause they aren't there anymore
Still exists ...
Couldn't work out why it wouldn't let me put my MX records in.
Thanks. This got me to the "Add more to this record", and even though it's a multi-line text field, only one record per input field allowed (keep hitting the 'Add more' button for each extra record).
This post was the only resource I found to answer this question. Thank you! This is such bad design on Google's part!
Thank you so much! What is
Thank you so much! What is exactly I look for.

Big thank you!
You are one of the heroes that do not wear capes.
I dunno how I stumbled upon this, but mine was the second option... the + sign... I NEVER woulda figured that out. Thanks a ton!
Same issue with adding TXT record. Thanks for the solution
Amazing thank you, helpful!
Amazing thank you, helpful!
Excellent guidance. Thorough and well reasoned. Thank you!
thank you so f much
it's been years i have been trying to resolve SPF/TXT records and kept being forced to concede there was only one record possible. how insane is this UI and that NOBODY else has pointed this out anywhere.
Yet Another Thank You
You're the best! Literally nowhere else on the Internet had this info that I could find, except for you, and your advice fixed my problem. Thank you, internet hero!
THANK YOU SO MUCH
Thank you for this.
You know sometimes something obvious takes so much time to resolve, and these kinds of solutions are time saving.
Thanks for caring enough to share this
This was exactly what I needed to do! Thanks.
This post saved me lots of time and headaches and I am so glad I stumbled upon it. We have a client with their domain registered with Google and everything has been a bit of a hurdle so this was very helpful.
Dude. You're smarter than Google. You understand where they don't. Much appreciated!
You saved my life, haha, jk. This post was really helpful!
fixing error with DNS TXT record "already in use".
I had exactly the same issue-- @ and txt. I spent quite some time trying to figure this "record already in use
" situation on different forums and found your article on Google. I just fixed it and was finally able to add the new records! I am so relieved.
Thank you so much for the great tutorial and explanation into details. Life saver! Really appreciate your work.
You saved some hair-pulling, Phil.
3 days of trying to verify Stripe to enable domain email and I finally found your post. Never noticed the "+" before in Google Domains and wouldn't have thought to do anything other than trying to add a new, individual record. Thanks!
It is terrible that Google made a simple task an extremely annoying problem. Thank you for positing your solution in very clear steps.
Dude you rock!
You're an absolute star
I was just about to give up with this and then found your superb, wonderfully simple explanation and instruction. You deserve a medal! Unfortunately I can only give you a star (as I save your page to my bookmarks). Thanks so much.
You are the man!!! Thank you
You are the man!!! Thank you for this step by step!
Thanx so much. Very very helpful
