Bend Plane

I am trying to make a shape like this


I drew an SVG and tried to extrude it based on the top view. That works well. But in the front view, the plane has no bend. The downward bend part we see is parallel to the front face. I guess before extruding I should bend the inner part down without affecting the front face. But I don’t know how to do that. Any advice will be great. Thanks.

This is what I have now

This video helped. I was doing it the difficult way. I had to draw a plane, go to edit mode, select vertices of an edge and extrude it. The ctrl + B for Bevel and mouse scroll gives a smooth edge. Selecting vertices in edit mode gives control in adjusting the plane angle on different axis. Thanks.
