After you file

First, you must be inside your 2019 Online tax file somewhere...not just in the opening home screen.

 

Then, it's on the left-hand side menu   (if on a phone, you'll have to hit the hamburger stack....but please don't prepare and file on a phone...use a full computer or tablet with a large screen)
