I removed all the obvious bolts/screws from panel. It seems that there is something holding the door panel on behind the door lever - I cannot tell how it is attached?

I'm sure it has to be commen on most current compact/sub compact chevys?

Does anyone know how to remove it?

 

This is for the rear side door inside panel replacement on a Hatchback 13 sonic

There should be a bolt by the inside door handle covered by a plastic cap. use a pocket flat blade driver to pop it out. then there is a bold under the inside armrest handle. (The oh crap handle) remove both of those bolts. get a wide (preferable plastic) prying tool and pry the door panel out by the speaker location. there should be plastic push clips that just pop straight out. they have a ton of resistance so once you get enough room get your finders in there and rip away they will make loud tap noises when the let go. This is from memory but its a simple door panel.
