Thanks Diane! From another thread I gleaned that I'd owe $$ to Virginia only if the business incomes was "sourced" in Virginia.
I work 100% remote and the only time I'm in VA are for client meetings (and I deduct those miles!) So I think TurboTax (and you) are correct that I really have zero tax visibility / liability to VA. Of course, TurboTax does include the (empty) VA return every year in my "return to file" PDF and tells me to mail the generated Virginia form (and thus far I've filed it with no complaints from Virginia).
