On a computer (not a phone/tablet running a mobile browser) load the Fi webpage and scroll down to the bottom.

In grey type on a lighter grey background, in small type, it is easy to overlook.

Next to Help Center there is a link to Google Voice. Click this to get into GV and check forwarding (if any is set) for your line.
