When you're doing the returns you need to do the nonresident state first. Wisconsin has all of the income allocated to it automatically and you need to go through the step by step interview and manually allocate all of the non-Wisconsin income to the home state. Once you've done that then you can start on your resident state return.
For interest income in the Wisconsin return you need to go to the Miscellaneous section and click 'Wisconsin NonTaxable Income and enter the interest amount there. It will remove it from your return at that point.
The nonresident tax return may reflect interest income from your resident state if the interest income wasn't allocated to your resident state. There should be an apportionment schedule that you can complete in the nonresident tax return where you can apportion the income that should be taxed in that state.

Thank you for the reply. I cannot find anywhere in the software where I can allocate/reallocate the interest income to the my primary/resident state (MN). TurboTax is automatically pulling in the interest income to the 'Income Allocation Worksheet' for the nonresident state WI form (1NPR) and I am unable to make any changes.
To clarify,
Did you import or type in the 1099-B
Was there any state tax listed on the 1099-B?
Thank you for the reply KrisD15.
I manually typed in the 1099-B (1099-INT) information from my broker. There is no State designation anywhere on the document - other than in my name & address at the top of the document, which shows my primary residence state (MN).
