Are you a resident of FL ? MN taxes you if you are still considered a MN resident ... read up here : https://www.mncpa.org/publications/footnote/2020-12/working-from-the-beach-minnesota-residency-and-u....
Now if you are not a MN resident ... then look at the last paycheck stub ... did they actually withhold for MN and you failed to notice this all year and have it corrected earlier ? If so you will need to file a MN non resident return to get back the erroneous withholding. Put the same amount from box 1 in box 16 so you can efile the fed & state.
Next if you are still working for this company please make sure they stop this practice and refund any MN withholding now while it is an easy thing to fix on the first quarter payroll reporting.
