Well, probably a number of thsoe things are not critical..
BUT..always a But.
A couple things I can think of:
1) IF you itemized deductions last year, you will need to enter the proper State refund for possible inclusion as federal income for 2022.
2) If you owe too much balance due this year, the amount of taxes you pre-paid last year, and whether you had a balance due last year, may become critical in determining whether you owe an underpayment penalty this year.....that would have to be recalculated based on your proper 2021 file.
3) Your 2 and 5-year history report is now messed up for last year's values.
4) Any credit carry-forwards?? Home energy credits carried over?
5) I would imagine, Excess charity donation carryovers are pretty rare.
what else??
6) exercise of ISO or NQSO shares last year...with some AMT credits coming into this year might be screwed up....(but I'm waaaay ignorant of what goes on there, not having any for 20 years)

Personally, I'd start over...but that's just me.
