I filed the Partial Year / Non-Residency form in Hawaii,
The above statement is contradictory and makes me think you checked the box on the N-15 for non-resident. If you were a HI resident the first part of the year, then you should have filed a part-year residence return with HI - not a non-resident return. In other words, on the N-15 you should have checked the box for part year resident; not the box for non-resident.
I can't speak for MT forms, because I'm not at all familiar with them.
