HOW TO: Move Characters / Overlays to the Layers

Can someone PLEASE help me… I’ve been working on this thing for 3 days now and I can’t freaking place this overlay…

I can’t put a positive number for the shift of the desk, the value doesn’t even exists. I know -326 -7 means it’s in zone 1 but hell, I don’t even understand what’s going on here now… Please, help
