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.
