I found it using my phone’s browser and I can’t remember how different the mobile page and desktop page are, so YMMV, but:
I clicked my name and a menu popped up. On that menu under “Your Account” I clicked “See all options” and it took me to a page that had “Hello” in the upper left, and beneath that a link that said “About You”, which took me to the page with that stuff.
