Get your taxes done using TurboTax

Conceptionally, I understand what does carry back do.  And I saw I can input a loss for the "carry back".  But how do I amend the 2021 return for the carry back I entered for 2022 return?

 

I used the TurboTax Premier desktop version for both 2021 and 2022.  When I am doing the 2021 amendment in 2021 TurboTax Premier, where do I put in the carry back amount?  Thanks
