I had 20GB of message attachments I just deleted.
1. Go to Finder.
2.
Hit the Command+Shift+G
3.
Now enter the ~/Library/Messages/Attachments/
You’ll see the attachment files listed randomly. Select files and delete them as usual.

Thanks for your help, not much could be found, did the next best thing, wiped the drive. I installed Catalina 100 Gb gone, I run on an external, internal is original. {2018 mini}. At 75 years of age I do not appreciate Apple screwing things up when they change OS. I have been with Apple since Leopard or earlier, If they can't figure how to make things work leave it the hell alone. Tom

I use DaisyDisk to visualize what's taking up the most space and delete as needed. Highly recommend it!

I just remembered how I discovered my large folder of message attachments. This would also work to find your culprit.

Option click Go > Library > and I selected all 78 items. Click Command + i to Get Info on all the items. Once there I looked for folders with huge files until I found the massive archive of old text message attachments.

For me, it's the Xcode that wasted almost 40 GB in "Archives" folder (~/Library/Developer/Xcode/Archives) and 40 more GB in "iOS DeviceSupport" folder (~/Library/Developer/Xcode/iOS DeviceSupport). Around 100 GB in ~/HD/Users including an old version Xcode inside the Shared folder
