I have a to file tax returns in two states. I also have dividends from treasury bonds that are exempt from state taxes. I was attempting to complete the non-resident return details and it asks what amount of the deduction from the t-bill dividends should be applicable. It should be 0 because I didn't live in that state when I earned the dividend. It asks for a positive adjustment as a negative number and a negative adjustment as a positive number (the wording is weird but that is irrelevant).
If X is the amount, when I put -X for a positive adjustment, the deduction is still credited to that state.
So I try +X, and I end up with a -3*X deduction.
I try 0, I end up with a -2*X deduction.
Realizing the pattern, I enter -2*X, and this somehow translates into no deduction for this state (and then properly allocates the deduction to the other state).
Clearly some issues with the +/- calculation. Hope it can be resolved and help somebody else in this scenario. Happy to provide additional details if necessary.
