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).
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.
