No you cannot.   When you use TurboTax the information flows from the federal return to the state return.  You say you already filed a federal return using a different software program.  You will not be able to file a federal return using TurboTax nor will you be able to e-file a state return.  TurboTax cannot be used to prepare a stand alone state return.

You could go on your state's tax web site to prepare and file the state or get the state forms to prepare and mail.

You will need information from the federal return you filed.
