Q. Where is the spot to put in a tax home or exempt from state income taxes?
A. There is no such spot in TurboTax, nor on most (if not all) state tax forms. If you're not subject to state income tax, you just don't file for that state.
But, as TomD8 said, you are most likely subject to state income tax where you work.
