What do I do if I live in Wisconsin but worked in Minnesota for a short period of time and I’m submitting my income taxes right now

You must report ALL your income on your Wisconsin return, including what you earned in MN.

To determine whether or not you also need to file a MN non-resident return, see the MN "Filing requirements for part-year residents and non-residents" on page 6 of this reference:
