Photos edited in Photoshop disappeared into lightroom

Hi- I created two virtual copies of an image and opened them both from Lightroom Classic --> Edit in Photoshop. I layered one on the other, spent about an hour editing, then clicked file--> save. When I went into Lightroom, the edited image appeared. I even took a screen shot of it next to the original. I came back a few hours later and the edited version is GONE. The copies are there but I cannot find the final version I saved from photoshop. I feel like I'm going crazy because it MUST be there somewhere but I can't find it, even when I search for the file name or all tiff images on my computer. Ideas? Feeling desperate.
