I ran into the same issue and here's how I fixed it.
Mar 26, 2020 Your Mac now has additional storage available in Google’s cloud to use as you wish. However, one of the best uses of any cloud-based storage system is to link the storage to multiple devices for easy access to synced files with all of your devices: Macs, iPads, iPhones, Windows, and Android platforms.

1. Went to the Finder -> Preferences and changed the 'New Finder windows show:' setting from 'All My Files' to my Home folder which is my Mac OS Login name.
2. Then opened a Finder window and OneDrive is listed there along with my other folders like Desktop, Documents, Downloads, Dropbox etc. If you selected the default location for the OneDrive folder during installation, this is where it should show up.

3. Then I just selected the OneDrive folder and dragged it under Favorites on the left pane of the Finder window.
4. You should now be able to open any new Finder window and see OneDrive in there. You can also drag it down to wherever in that list of favorites you want it under.

Good luck and hope this works for you.
