Where is the Convert Extrusion Command

I am completely new to Rhino and learning it from scratch on a Mac Book pro, Rhino version 5.3.2.
I have extruded a curve and would now like to edit that 3D surface using the points, but only two points show up that only allow me to rotate the surface
I have read that there is an Convert Extrusion Command that will alter this? Does anyone know where this command is, or how I convert the surface to have all the points I am after?

Thanks in advance

Just start typing ConvertExtrusion… should autocomplete. --Mitch
