I am trying to amend a 2021 tax return from married filing sep. to jointly with injured spouse form. I have my previous return, but I can't find form 8379.

I've changed it to filing jointly, just need to add the injured spouse part and it's not offering it anywhere that I see.

To reach Form 8379 in TurboTax:

1. Type injured spouse in Search.  
2. Click on Jump to injured spouse. 
3. Say Yes, you wish to claim innocent or injured spouse relief.
4. Enter the Year (usually the current year).
5. Skip the fill-in screen for Innocent Spouse Relief by clicking Continue.
6. TurboTax will begin a series of questions to see whether you qualify for relief.
