I've looked back over all my records, and my return accurately reflects the quarterly estimated payments I made in 2021. As I dig deeper into the amount that the state has adjusted to (vs. my total on the return), it is the exact amount of one of my estimated payments - the first one that I made in April. It appears they aren't giving me credit for that payment. But I have a copy of the cleared check. More and more I think they have made a mistake.
