How do I find the buttons to begin an amendment for a tax return.

  You have to access your own account and/or  print it for yourself using exactly the same account and user ID that you used when you prepared the return.

 

Start a 2022 return online and enter some personal information  so that the menu on the left opens up and lets you access your past year returns.

Many people have multiple TT accounts and forget how to access them.  Log out of the account you are in now.

Or did you use the desktop version of TurboTax?  If so, the files are on your own hard drive or any backup device you used like a flash drive.

To get a copy of your previously filed returns prepared with online TurboTax https://ttlc.intuit.com/questions/1900748-how-do-i-get-a-copy-of-a-return-i-filed-in-turbotax-online

you can only amend the year that the software knows about (this year for Online).

if you want to amend prior years, you need TurboTax CD/Download version for that year, or get the amendment program from Customer Support.
