I also found an error.
On Iowa 1040 Schedule 1, Line 14 (Federal income tax refund received in 2023) should be reduced by any refundable tax credits. Iowa doesn't tax refundable tax credits.
In the TurboTax 2023 interview (Iowa), the American Opportunity Credit—2022 Federal Form 8863 Line 8—is missing from the list of refundable tax credits. Thus, TurboTax 2023 would have me pay tax on that amount, thereby overpaying my 2023 Iowa income tax.
Since the interview has no line on which to enter the American Opportunity Credit, I entered it into one of the other lines.
I only found this error because, in addition to TurboTax Deluxe 2023, I used H&R Block Deluxe 2023 and saw the difference.
