Hidden videos

On my iPhone 7 running IOS 13.3 iPhone storage under Settings shows and inordinate amount of space allocated to media. I hooked my iPhone to my PC via the USB port and ran the iTunes app on the PC. It shows 7.16 GB devoted to videos on the iPhone, and reports there are 3 videos. However nothing is listed under Movies or any other "On My Device" category except for a few songs under "Music". On the iPhone the storage report under settings shows no app coming anywhere close to 7GB for data and app combined. I've check under the TV app and there is one movie purchased but not currently downloaded. I have downloaded a few movies in the past but had deleted them (or at least I had hoped).

Any idea how I can find these 3 videos and delete them to free up space? I'm not out of space but its only a 32GB iPhone so 7GB is significant to say the least. Thanks.
