For me, it's because the Minnesota update deletes the Grade fields on the MN M1M "Deduction for K-12 Education Expenses Worksheet". Without the Grades, the deduction goes away and the calculations are messed up. This is the 2nd year in a row that this has happened to me when I went back in to print my taxes after they were accepted and I stupidly let it update the program after already filing my return.
