What is this folder within the private folder and why is it massive?

I am looking to see why my mac is running out of storage and I saw my private folder was 54GB and within that (private>var>folders>wn>zk6z68gn17j9525rgOthcyy40000gn>T) this folder is responsible for it. However when I look into the folder "T" and sort contents by size, they do not add up even close to 51GB... Any info from anyone on what this directory is, why its so large, and where are the contents responsible for the size. See attached screen shots for ref.
