I got the latest updates yesterday, including the updated Form 2210. I have found 5 problems with how TurboTax is completing Form 2210 on the tax year 2021 deluxe edition for the desktop. The first issue I can work around, and I can override the TurboTax calculations directly in the form for all four of the other issues, but in three of the cases, TurboTax considers it an error and I'm not sure what the consequences are for e-filing my return with these overrides (assuming it even allows it).
1. In the Step-by-Step questions for determining if there's an underpayment of taxes (and the penalty, if so), TurboTax specifies the wrong time periods for specifying your withholding. It asks for the 2nd quarter ending on 7/15 and 3rd quarter starting on 7/16, whereas the dates on the IRS Form 2210 are 6/15 and 6/16 respectively. I can work around this issue by entering data for the 2nd quarter ending on 6/15 instead of 7/15, and the 3rd quarter starting on 6/16.
2. Form 2210AI line 7 says to add line 12b from your 1040 form to your standard deduction. TurboTax did not add line 12b.
3. It's a flaw that TurboTax does NOT ask for qualified dividends by tax quarter, as it does for withholding. It puts the entire year's tax dividends in the last quarter, potentially resulting in higher taxes due in the first three quarters. In this case, I could override the values on the form without TurboTax flagging it as an error. At a minimum, TurboTax should flag this situtation as one you might need to override.
4. TurboTax incorrectly copied the value from Form 2210AI line 27 for Form 2210 Part III line 10 for column a. It did correctly copy the amounts for columns b, c and d. I have no idea where the incorrect figure for column a came from… clicking on the link to the data source shows the correct value for column a.
5. Form 2210 line 11 is wrong for column d. It understated the total of the estimated taxes plus withholding for that quarter. This was the only quarter for which I paid estimated taxes since my withholding was sufficient for the first 3 quarters.
I also have a problem that the TurboTax error check during the Federal Review is asking me to enter missing information for Schedule 8812 Advance Payments received. I don't know if this is related to the Form 2210 issues or not, but I don't have any child dependents, so this form certainly does not apply to me. Also, TurboTax correctly does not include this form in the saved PDF file with all records for my return. So why does the Federal Review think I need it?
