I see the path and it is in the Photos Library.
Earlier today I deleted the photo library file by unsyncing from Amazon and then I synced it again until it was back.
Throughout the day the trash bin rose to 3,000+ files. Then I saw it go down to about 800. Then, when I wrote this original post it was at 3k+ again. AS I write this post, the trash bin files are at 1,230 and decreasing.
I will continue to monitor this.
