I see 3 categories:
1. Favorites , which includes dropbox, all my files, Applications, Desktop, Documents, Downloads, Movies, Music, Pictures
2. Shared, which lists my Time Capsule along with an external usb external drive connected to time capsule
and
3. Devices which includes "Remote Disk" (whatever that is), WD Smart, My Passport, and LaCie external drive
There's no sign of my internal SSD
Open Finder then hit command-comma and check the box I marked in the preference pane. That will make your computer show under Devices in Finder. Then in Finder click the computer name now showing in Devices. That will bring up Macintosh HD in the right pane, which is your main internal drive partition.
All the things you listed under Favorites above are different folders on your internal drive though.
