State tax filing

I inherited royalty interests in oil and gas properties in Montana. A small payment was received by the estate in 2020, I had to hire an accountant there to file a federal return and issue a k-1 to the heirs, which includes me. I am now completing an almost blank MT nonresident return in Turboxtax and uploaded the K-1 as a PDF. I entered the amount of the income, but see nowhere to enter into TurboTax the tax withheld. The amount withheld exceeds the tax due, and I can't see how to claim a refund. Instead, Turbotax says I owe tax on the income. Where do I enter it?
