You are filing in Virginia only to get a refund? No taxes are owed? So it doesn't really matter which county you pick. The Dept of Taxation will pay the refund.

A couple of years ago there USED to be an "out of state" answer to this question, and for some reason this option vanished! So I have been using my own Virginia county (Rockbridge) and figured that the local Commissioner of Revenue will sort it out. Especially if no taxes re owed. Perhaps this is not a ProSeries issue, rather a Virginia Dept of Taxation irrational change.
