I think TurboTax made a mistake in my estimated taxes for state and double counted the prior year overpayment. I don't see how to fix this.

This is for Mass. state taxes. I see the same amount given in form1 lines 39 and 40. When I jump to the worksheet I cannot alter either amount, and I don't see any other way of changing this. The information must have been transferred from last year's return.

Look at what has been entered for your state estimated tax payments using this procedure, edit or delete as needed.

Thanks. Yes, of course it was my mistake. On the (Federal) page where I report state estimated taxes, I had entered my 2024 overpayment as an "Additional Payment" even though it explicitly said "Don't enter payments made in 2025 for your 2024 state return or any 2024 overpayment applied to this year's return."

I have two suggestions for improvements:

The "Don't enter..." should be closer to the field for Additional Payments" (rather than at the top of the page), and;

When I click on (and try to edit) the entries in the state tax forms, it should explain that this value was transferred over from the federal taxes, and point me where to go to change it.

Thanks so much
