You may be referring to the cost of e-filing a state return, as opposed to a free state software download. There is a fee for e-filing your state return.
See the TurboTax Help article Is there a fee to e-file my state taxes in the TurboTax CD/Download software? for more information.
Depending on the TurboTax Desktop product you purchased, you may get one free state download. That's the software that you need to create your state return. See Which TurboTax Desktop software product is right for you? for buying options.
If you have a free state download, you're welcome to print and mail your state return to avoid the e-filing fee. See the TurboTax Help article How do I print a copy of my tax return in TurboTax?? for more information.
