No. The taxpayer was a part year resident of Minnesota then a resident of Kansas. The tax exempt income was Kansas based causing it to be an addition to Federal Taxable Income totaling on line 3 of the Minnesota M1.

The error detail states:

On form M1, line 8 Minnesota Taxable Income must equal line 4 Adjusted Federal Income minus line 7 subtractions to line 8 must not be negative.

Problem is that line 9 is Minnesota Taxable Income which includes line 1, Federal Adjusted Gross Income + non-Minnesota tax exempt interest from Federal Schedule B. That total is on line 3 of the M1. Proseries is taking M1 line 1 - M1 line 4 = Minnesota Taxable Income. It should be M1 line 3 - M1 line 4 = Minnesota Taxable Income.
