TurboTax cannot be used to prepare or file a "stand alone" state return. The information flows from the federal return to the state return. If you already filed a federal return elsewhere, why did you not prepare the state at that time using that prep service? You could use your federal return and prepare the state return yourself by hand. Get the forms from the state--or see if you can file the state on the state site.
