Finding what is using storage in your home directory/folder:
du -hx $HOME | sort -h # This will take a few minutes
The 'du' (disk usage) command will show storage being used in every
folder under your Home Folder. After checking for local APFS
snapshots, there is a reasonable possibility your Home Folder tree is
where most of the storage is being used. You can specify other
starting folders.
