That makes sense. I did pay $35 with the amended return, and expect the 2020 $90 overpayment will be applied to my 2021 estimated taxes. However, you did not adequately address why TurboTax modified the original state return by subtracting $35 from the $90 (thus only $55 overpayment to be applied to 2021 estimated taxes) AND prepared the amended return with the $35 payment. Math says the amendment cost me not $35, but 2 X 35 = $70. I am so so concerned with the accounting at the state tax office, as I am with TurboTax i.e. when I do my 2021 taxes and import the 2020 taxes.
