By paying $24.99, how many e-file returns to the same state do I get, i.e., is it $24.99 per return or is it like the federal e-files that you get 5 of them?

If TurboTax charges $24.99 per return to e-file state returns, how can I switch from e-file to mail filing?  It gives me NO opportunity to change to mail filing the state return, once I've chosen e-filing for the federal return.
