Intuit has just made an announcement that fill-in forms will be available in PTO starting Feb.  It's just not clear whether all forms not currently included with computation will be included.  Guess we'll need to wait and see.

F.3520 is a dummy form that has to be filed separately on paper anyway.  So, I'm not too worried.  Of course, it's still best if we can have all the forms in one place under PTO.
