Often some state forms lag behind the IRS forms, so it is possible that SC doesn't have all of the forms you need ready to go. You can use the tool I'm linking below to check on your forms availability. Once you've successfully e-filed your returns, both should be available to print.

Has your federal e-filed form been accepted by the IRS? If you haven't e-filed your state return yet, you'll now need to wait until the federal return has been accepted to e-file your state return. This is a security measure.
How do I file my state return after I've already filed federal?
If you DID e-file your SC return (and forms weren't all ready), TurboTax should contact you when all forms are ready so you can complete your filing.
As for the charge to e-file your state return, you should not be charged again. If, by chance, you find that you have a duplicate charge, TurboTax will quickly refund your overcharge.
Why was I double-charged or billed twice?
