I found a workaround. Keep pressing buttons, trying different routes through TurboTax. As I recall, I just said to file again. After a bit, TT told me that Fed was already filed and accepted (true), then went ahead and filed State after I paid them for the privilege. Just pretend you haven't filed Fed, start fresh. If that doesn't work, try something different. Something worked for me: Fed one day, State a week later.
