How do I calculate "Income from Virginia sources" as a nonresident for Virginia state taxes?
I am a resident of Washington state, but worked for a bit while on vacation in Virginia. How do I calculate nonresident income allocation for my Virginia tax return? The only guidance offered by TurboTax is "Enter the portion of the following items that you earned in Virginia (or from Viginia sources)" but it doesn't explain how to find that portion.
TurboTax doesn't seem to support this scenario. Would I be better to directly fill out VA form 763 and file it directly?
