When I change VA income to $0, it gives me the electronic filing error - "box 17 entry is not valid".

The only way I seem to be able to do this cleanly, although it still may not be correct, is to change the allocation on the non-resident allocation percentage section of the 763 to $0, which then refunds all the withholding. It's essentially going around the butt to get to the elbow, but it worked. Is that what you were getting to from the beginning? Or does it not sound right?
