Galaxy 9+ internal storage filling up even after reset

[Android Central Question]

After my Galaxy 9+ filled up even with minimal apps and no photos/vids/music on the internal storage, I did a reset and re-loaded all my apps and then some. Once I did, it showed 20% of the 64GB available on the internal storage and the SD card about 50% full. Great, the phone was operating faster again. Now 2 months later, the internal storage is down to 1-3% and I am clearing cache and moving apps to the SD card twice a day just to keep it from overloading.

The math doesn't make sense...there is some sort of phantom files eating up my storage but I can't find them. What do I do?
