I recently learned about how to deduct HRA reimbursements for 2021. That triggered the need to amend my 2020 return, which I did following the instructions using TT 2020 and the Amend button on the home screen. I modified my medical expense numbers, and said that was all I needed to amend. I previewed my filing as a pdf, and noticed that in addition to reducing my overall itemized deduction (as expected), my AGI was reduced by $10,200, with the result being I am owed a refund of $1038. This makes no sense to me; I expected to need to pay a few hundred dollars back of the refund I received last year.
How can I resolve this discrepancy?
