No problem. I'll use another node:
nodetool listsnapshots

Total TrueDiskSpaceUsed: 11.44 GiB
I just picked one directory:
pwd
/mysqlData2/cassandra/doc/doc-f4845f60fd2311eab6e21593630dfb58
du -s -h ./*
12K ./backups
142G ./snapshots
I've not cleared the snapshots from this node - let me know if you want
other information.

That said, the "Total TrueDiskSpaceUsed: 16.09 GiB" seems to be
way off? Or is that value something else?
It's a bit late now since you've cleared them but it would have been
good to check the size of each snapshot directory with duand validate
it against the listsnapshotsoutput.
FWIW snapshots are hardlinks to the same inodes as the original files.
I've explained how it works in this post --�
