Samsung Full Storage glitch

So my Google account had filled up on Google Photos, so I was trying to delete everything. I thought I may have had found a means do delete it all at once, but it started deleting anything from my phone gallery that was backed up. I stopped it about 3/4 of the way in once I realized. I them went to settings > Device care > trash, to restore what was set to delete. Unfortunately, I don't know what exactly happened, but it didn't put any of those photos back in the gallery, but they are not in the trash, and now I'm getting notifications when I open my phone's camera, that it's unable to be used due to my storage being full. I put my photos from my phone on a USB drive, then delete the majority of them from my phone gallery, but I can't figure out where the photos are that ate taking up most of the space (the ones that were sent to trash via Google Photos). Help, please!
