Amending a return

I filed my 2020 return before the unemployment tax change. 

I went into TT to amend it and TT already fixed it. 

TT amount is more than IRS figured and I want to send in what TT corrected.

I clicked on amend a return but new return comes up.

How do I pull up the prior return I filed in March to amend it to what TT fixed ?? 

Thank you in advance for your help.
