State tax filing

Florida does not have a state income tax.   People who have Florida businesses or rental property with tangible personal property have to file a DR-405 with the county property appraiser by April 1.

If you don't have a Florida business or rental property with such tangible personal property, then you do not have to file a Florida return.  If you are still preparing your returns, you can delete the Florida return if it's not needed.

If you've already finished and paid for it, you can talk to TurboTax Customer Support and tell them you didn't need it.
