I found out that one of my previous employers for 2022 submitted a corrected W2 (naturally without any notification) and it looks like the changes were to Box 12 on the W2:
Original: Box DD = $5085 Box W = $0.00
Corrected: Box DD = $9730 W = $3000
I normally file with TurboTax and when I tried inputting these numbers, I noticed that it didn't change any of the refund amount (owed or due). For context: we had a high-deductible HSA plan where we did use all of the contributions for medical expenses in 2022, so I think it cancelled out any taxable HSA contributions.
I looked over the amended the docs for the new return and it looks like the Net Change looks like $0 for federal/state. I was wondering with that being the case, is it generally even required that I submit a return?
