I ran into this with RI too. The issue is with NC, not with TurboTax.
Choose the file fed form option, but not the state, for now.
That way you can at least get your fed taxes filed.
Come back after the 24th of the month and NC will be ready to accept electronic returns.
When I had the issue in RI, I simply tried it once a day until it finally transmitted.
The state of NC is saying the 24th, but it could be sooner. RI had been saying the 25th, but started working early this week. I'm not sure if everyone reading these messages realizes it, but this is a community board.
The people responding are like you, just users of TurboTax, not TurboTax employees.
