I have been having this problem of late after finishing doing a back up: I select time machine with the cursor, giving focus to its little green HD icon, then “right click” on it and choose “Eject Time Machine.”
… (the minutes go by)
Nothing
…
Again: “Eject Time Machine”
….
Nothing
….
Try ejecting from the Finder
Nothing.
Say things you are not allowed to write here and unplug Time Machine, to the howls of horror of the OS. (An alternative, and, I am told, also a questionable one, is to “Force Eject” TM.)
Well, that is my story so far.
Looking around in the Web, I came up with several suggestions less than a year old and of these, the least potentially fatal advice I have found is here:

In particular the one comment about using the Disk Utility.
To be clear, I am running Big Sur, and it seems this is a Big Sur bug, so the practical idea seems to be to use some working and workable workaround to bypass this bug.
I shall very much appreciate the opinions of people here who may be familiar with this problem. Thanks in advance for any practical advice.
