"Why am I being ask to file FL state tax return when FL does not have state income tax?"
The Florida return in TurboTax is to report tangible personal property that is used in a Florida-located business or rental property and is filed with the county property appraiser. You should have been presented with the opportunity to skip the Florida return entirely if you had no tangible personal property to report.
If you proceeded past the warning screens, try deleting the Florida return --> https://ttlc.intuit.com/questions/1900608
