However, I was trying to compare my system with the OP's and noticed that I have a directory with >2TB of used capacity in a folder sized ~36kb - a 56793929:1. In the OP's situation, he has a directory with ~2.8MB of used capacity in a folder sized ~2MB - a 1:1 ratio. That's the part I'm confused about. Without knowing what the OP's file system but assuming he too is using EXT4, what would the directory be storing that's so different from mine?
