After you file

Nope.  Incorrect.  On one page only, I was able to access "My documents."  Once there, I was able to select my 2018 tax return and when I clicked "download pdf" i was prompted to return to the page for filing and select a product and was further explained that to access those documents I'd have to upgrade to plus or premium or something.  

Furthermore.... SINCE then, I haven't been able to access my documents.  There is not a menu for my that says documents on the left hand side of the screen as the help articles indicate.
