Devices/Sync/Duplicate
I found this looking for help with my question:
I see duplicates in the Devices & apps list
If you see devices listed multiple times (and you're sure that it is the same device) in the Devices & apps list, click the Disconnect button next to that device to remove it.
MY QUESTION: What if I am NOT SURE it is the same device? Thank you

The best way is to disconnect all devices you are not sure about. Then start those devices and re-enable them to sync. Any 'bad' devices would be removed.
