If I can't get past the "Review your local info" screen because it won't accept the county entered and keeps displaying "Select a county" in red, how is this resolved?

You're seeing this in your state return, correct?  Are you entering the county name manually?  If so, see if there's a drop-down menu of counties and select the county from there before proceeding.  

It's a shot in the dark, but may work.  Hope so.

That's not working still stuck on the screen.
