After you file

No, you can't amend if your return if it was not accepted by the IRS.

If your 2021 return was not accepted, and you didn't print it and mail it in, it is not yet filed. 

The good news is you can fix your return before your send it. The bad news is you can't e-file it at this point. 

If you used TurboTax Desktop (from a disc or download), you can simply open the 2021 program, select Fix my return, make the changes you need to make, then print, sign and mail it in in.

If you used TurboTax online:

1. Sign in to TurboTax using the same account you used in 2022.
2. On the home screen, scroll down to Your tax returns & documents and select 2021.
3. Select Amend (change) return.
4. Follow the steps to download your return and the 2021 TurboTax software. Don't try to open your return until after you install and open the 2021 TurboTax program. 
5. Once you have the software and your .tax file, click Find a tax file toward the lower right corner on the first screen in the software.
6. Use the pop box to search for and open your .tax file. 
7. Open your return, make the needed changes, print, sign and mail in your return following the directions in the program.
