If you used TurboTax software to prepare the state return you fee is the same whether you e-file the state return or mail it in an envelope. The fee is for using the software--not for e-filing. If you want to delete the state return and prepare it some other way you can do that. Your state might have a way for you to use the state's site for free; or you could print out the state form to prepare on paper by hand to mail in. Make sure you have a copy of your federal return handy because you will need information from it.
