How to create curve on an angle AKA push pull curved surface

From the file attached i have a corner, what would be the best way to keep that angle and fill the curve?Sketchup scale 2.skp (139.3 KB)

Solved.

This saved allot of time.

Not sure if that front lower edge should be sloping or if the whole bottom face should be on a single plane? ( the red wiggly line over that black line is a line that should be red?
I tried joint push pull but because of the top slope it didnt seem to work.
I used find centre arc (or offset) to get curved edges and then used the curviloft / skin contours on each face.
