iPhone 11 system data taking up excessive storage

My iphone 11 keeps saying storage is full. I have already deleted text attachments and texts, deleted and off loaded apps, cleared web history and cache. I've done all the things. I think the real culprit is system data that is taking up 38.83gb. I am updated to the latest update, I have cleared out photos, emptied all the recently deleted folders and I still cannot get it down. Any suggestions? (I have deleted all large attachments. When you tap on it, it is empty, but yet keeps saying there is attachments.)
