I'm unable to file MN return electronically due to mortgage interest value on form M1SA. I have no mortgage interest or points to report. Showing blank on Federal Schedule A and zero on M1SA. The error message says "Home mortgage interest should not have a value since federal Schedule A, lines 8b and 8c are blank. I deleted the "0" but it kept coming back. Help please. I don't want to mail it in.
