The first place to look would be to check your e-file status at the link below. This page will show both your federal and state e-file status. If your state return is showing as "pending", then it's been submitted and is just waiting for a response from the agency. If it says "Rejected", then you'll want to go back into TurboTax and e-file the state again.
