amending return for Trad IRA contribution not made

On our 2021 return, my wife just informed me that she actually didn't make the $4000 Traditional IRA contribution that she was supposed to make (in early 2022, before I filed our return).   Thus, I need to amend our return, and I am having trouble getting Turbotax to do the right thing.

 

I fire up Turbotax, go to "other tax situations" and "amend my 2021 return".  Under "what do you need to change", I needed to pick "different reason", and then "deductions and credits".  So it took me to the part of the interview where you put IRA contributions.   I'd originally put $7000 for myself (correct) and $4000 for her (now incorrect).   So I removed her $4000, left my $7000, and proceeded.

 

The 1040 now correctly shows that our AGI is $4000 higher and that our tax bill is about $880 higher.   But the 1040-X is completely wrong.    It shows the new correct AGI and total tax in Column C, but it shows an amount that's $7000 higher in Column A.  I other words, it thinks I amended my return to include my $7000 contribution and that it wasn't on the original return, and therefore I'm due an add'l refund of $1500 or so.

 

How do I get it to do the right thing ?   I'm able to go in an edit the 1040-X to change the amounts in Column A to what the original return showed, but it doesn't seem like a great idea to do it this way.

 

I guess I could just change the original return to remove the $4000, and then fill out a 1040-X by hand, but I shouldn't need to do that.

 

Or just wait for the IRS to come after us ...
