Since upgrading to Catalina, 30 folders appeared in the Macintosh HD finder window. They were not there before. See below. They are dated between 2017 and 2018. I cannot drag them to the trash and when I right click, "Move to Trash" is not there as an option. There doesn't seem to be anything in these folders.
I have restarted, tried holding down command, option, control, fn, while trying to drag the items to the trash.to no avail.

That didn't work. I found a much simpler solution. I booted from an bootable external SSD that I had make with Carbon Copy Cloner. The folders were not present on the backup for some reason. I was then able to go to the internal Macintosh HD and delete the folders. I did have to put in my password to do so but it worked like a charm.
They are likely stored on the Read Only volume.
You would need to use Single User mode to remove them via the Terminal.
Start up your Mac in single-user mode or verbose mode - Apple Support
I didn't know what to do once got there. I have no idea how to remove files via Terminal.

Yep, that'll make that rather difficult, then. I don't like to explain how to do it, either as it could result in deleting things you didn't want to delete. Too easy to make a typing mistake.
What didn't work about Single User Mode?
