After you file

I assume this is a 2018 return.    You didn't say if you have already filed the Federal return or not, and if so, was it by efile or did you print, sign, and mail the Federal return?   

Why are you printing the Federal return--for a copy after efiling, or printing to file by mail?

 Florida does not have a state income tax.  There is no "state return" per se.  There is a Form DR-405 that some Florida filers need who have Florida businesses or rental properties with tangible personal property.  The DR-405 has to be filed with the county property appraiser by April 1.  

If you started a state return you didn't need, then you can't delete it if you have already registered in Free Edition.  But you are not required to file it if you don't need it.  

First, if you don't need it, see if you can delete the Florida state return (if you haven't registered).

However, if you already registered in Free Edition and filed the Federal, then it won't let you delete the state.

If you still have trouble downloading your PDF at the Tax Home, then we can tell you a way to open the return back up and try to download/print at the Print Center.   If that doesn't work, we can tell you how to "fool" TurboTax by telling it you plan to file the state return by mail, even though you don't really have to actually mail it.
