"I am getting charged for Florida state tax preparation."
The Florida return in TurboTax is to report tangible personal property that is used in a Florida-located business or rental property.
If you do not have tangible personal property to report, choose Skip State in the StateTaxes section.
If you proceeded past the warning screens, try deleting the Florida return.
