Florida does not levy an individual income tax; there is nothing you need to file with the state (e-file, by mail, or otherwise).
The Florida return in TurboTax is for owners of businesses and rental real estate with assets to report. You should choose to skip the Florida return during the state section of the program.
If you proceeded past the warning screen and were actually charged for the Florida return, contact Customer Support (instructions below).
