The Florida return in TurboTax, Form DR-405, is to report tangible personal property used in connection with a Florida-located business or rental real estate and is filed with the county property appraiser's office by April 1st. If you need to file anything at all in connection with your rental property, Form DR-405 would be the return you would file (assuming you have tangible personal property to report). 

Check the state's web site for more information on the TPP tax. http://floridarevenue.com/dor/property/tpp/

Also check the property appraiser's web site for the county in which your rental is located. You should be able to locate your parcel (STRAP) number on that web site as well as information on the TPP tax and how to set up an account, if necessary. http://floridarevenue.com/dor/property/appraisers.html
