I revised some of the wording in my answer above, which should make it more clear that the Documents tab method is only to get a PDF. To get the *.tax2019 data file so you can open it in your 2019 desktop software, you will need to use Method 2 above; i.e., to go to the section "Your Tax Returns & Documents". With that method, too, you'll have to get past some preliminary screens (if you haven't already) in order to have a Tax Home tab.
