As TurboTax AlexanderS08 mentioned above, Florida does not have a state income tax. Here's some additional info, and if it does not apply to you, and if you started a Florida state return by accident, I've also left info on how to contact TurboTax Support to ask for a product refund for the Florida state return fee.
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 choose to skip the Florida return, or 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.
