I filled my 2020 Arizona state taxes with an overpayment of $90 to be applied to 2021 state estimated taxes. Later, I received additional documents in the mail that required me to amend my taxes, with the result that my state tax liability increased by $35. One would expect that either of the following would occur a) The overpayment was reduced to $55 and applied to 2021 estimated taxes. Or b) The initial overpayment was not changed (i.e. left at $90 and applied to 2021 estimated taxes) and $35 owed with the amended return. After amending my return by including the documents received in the mail, TurboTax revised my Form 140 to show an overpayment of $55 to be applied to 2021 estimated taxes. OK so far. However, the Form 140x shows an overpayment of $0, $0 applied to 2021 estimated taxes, and Amount Owed of $35. I am happy to pay $35 with the 140x, if it was clear to me that $90 was still going to be applied to 2021 AZ state estimated taxes, but the 140x does not show that, and furthermore, the revised 140 shows only $55 applied to 2021 estimated taxes.
