The IRS letter should tell you what was wrong.
Some possibilities----a LOT of people made mistakes on their 2022 federal returns due to errors they made with the recovery rebate credit (for stimulus checks they received) Line 30. or with the child tax credit. Line 28. Those errors would have had no effect on your state return, only your federal return. Were the mistakes on your return related to line 28 or on line 30 of your Form 1040? Did you answer something incorrectly about the amount of the stimulus check(s) you received or about the advance child tax credit checks you received?
