I am trying to free up disk space to install Catalina. I have deleted files using the storage manager and have also moved files to the trash and emptied the trash. However, my available disk space does not increase, even after deleting gigabytes of files. The amount of storage used for Documents goes down, but the total space used does not decrease.
The GUI is notoriously wrong or unrepresented in real time.
Highlight your Macintosh HD in the Finder or Desktop— Command i opens the info pane here you can see available/used storage

Try something likeOmniDiskSweeper for a GUI to get a good look at itemized file size and location:
OmniDiskSweeper http://www.omnigroup.com/more
Others for example—
Disk Inventory X: http://www.derlien.com/ (takes forever to load up.)
Grand Perspective: http://grandperspectiv.sourceforge.net/
Or alternatively from the Terminal.app, more detail copy and paste the command line:
File size, and finding missing GB— list the items in the home folder with the sizes, including invisible items.
sudo du -h -d 1 ~/
File size, and finding missing GB —will list the items in root with the sizes, including invisible items.
sudo du -h -d 1 /
