Are you sure you need to file a Florida DR-405 for tangible personal property? If you really need it (as discussed below), you may have to do it at the county property appraiser's website or through forms available there.
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 each year.
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.FAQ: How do I contact TurboTax?
