"Could not find this item" Trash problem?

Things I have tried

Searching original file location, but nothing comes up, and I just can’t delete it from any angle.

What I’m trying to do

Below, I am curious to learn how to get rid of this, as I have done nothing I would have character from my usual routine, which includes backing up everything simply by copy-pasting over into a separate external hard drive.

But now all of a sudden a chronically gives me this prompt warning, (Snapshot), I have tried from every angle to delete this, but it just keeps telling me it can’t find it, and now it’s just an unnecessary step every time I go to copy paste. Any ideas of what to do about this? Thank you
