We can check that there are, in fact, no unexpected subvolumes. btrfs sub list / In particular, I wonder if you have subvolumes/snapshots hidden behind the mounted subvolume. Also, I don't think it's really the case here with only 16GB reported by du,, but do you have any large, heavily fragmented files, such as VM virtual disks? Without defragmentation or compression, I've seen those consume more than twice their reported file size on btrfs.
