for 2020 the same thing happened to me but they have changed the layout of the page so the steps are a little different now. Select "Add Another State" as previously instructed to bring up your return - it is close to the bottom of the Tax Home page. The next options you need are now on the left side of the page (not at the top anymore). Select "File" from the options on the left side of the page and the page that comes up will show the status of your return and will also have a link to "View or Print your return". When you click/select this link it will bring up a printable copy of your return which will include the turbo tax cover sheets we all know and love...hope this helps.
