I finally solved this by spending an hour or so with Intuit support, who ultimately had me uninstall my installation and gave me a brand new product to install ...
I am having the same problem: program reports forms not available, but they are. So it won't let me file. This is a serious product defect, as far as I can tell...
I now see all these forms are listed as available on the TurboTax site too:https://care-cdn.prodsupportsite.a.intuit.com/forms-availability/turbotax_fed_windows...
