What should I do if some of my state taxes were withheld for the wrong state?

In 2024, I moved from AZ to CO. I am retired and in 2025, most of the state taxes I had withheld from a pension went to CO, but the state taxes for Jan. 2025 went to AZ. What do I need to do to get a refund from AZ and then pay those taxes to CO? I am using TurboTax Premier 2025 desktop on a Mac.

You will have to file a nonresident Arizona tax return and claim zero Arizona income to get the withholding refunded.

See Determining Filing Status for Nonresidents and Part-Year Residents

OK, thanks. Do I also need to do something for CO? That is, shouldn't the income that was reported to AZ somehow be reported to CO?

@kritter-k In your case, you were a full year Colorado resident for 2025 so Turbotax will include all your income (which is why you need to report zero Arizona income for the pension) so you do not need to do anything additional.  Because the withholding was sent to Arizona by mistake, you may owe Colorado a bit.
