What year do you want to file the state return for?
For the year that you need, did you use TurboTax Online or the CD/Download (Desktop) TurboTax software for your federal tax return? If you used TurboTax Online, see the reply from DoninGA above.
If you used the CD/Download TurboTax software, do you still have the software installed on your computer? Do you have the .tax20yy file for the federal return?
You cannot use TurboTax Online to file for a previous year. You will have to use the CD/Download TurboTax software for the year that you need. Exactly how you go about it will depend on your answers to the questions above.
