You should have encountered a screen telling you about the state return and who is required to file it, and one of the buttons should have said something like "Skip state return."
Florida does not have a state income tax. Only 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. You can delete the Florida return before paying and filing if it's not needed.
If you've already paid for it and don't need it as explained above, you can talk to TurboTax Customer Support and tell them you didn't need it.FAQ: What is the TurboTax phone number?
