Hit the same issue when amending 2020 return using 2020 TurboTax for MacOS. Even though the UI mentioned "Select Print Returns and chose "All official forms required for filing" to print out your amended returns". I don't see "All official forms required for filing" button anywhere. It's inconvenient to print 100+ pages and mail (also inconvenient to manually select updated forms from the 100+ pages).
Pls fix the problem!
