I received CP12 notice that explains why CTC and RRC were increased than what was claimed on my 2021 tax return.
Also, HSA deductible amount was adjusted (they said it is not allowed) by IRS to an amount $650. Therefore, the AGI was increased by $650.
Question: Do I need to re-file/amend MI state tax return due to this adjustment from IRS on Federal 1040? (Note: I already received my MI state refund for 2021 tax year).
Below link gives some info but it says to use Federal Amended Return and that's confusing as in my case there's no Federal Amended Return (or not needed since IRS corrected it already) !!
