I used loop cuts to add edges inside and outside the indentation, and then used the knife tool to cut across the indentation. The loop cut tool doesn't work because of the triangles on the side. However, where the indentation meets the surface, there are still triangles after cutting it. It seems to subdivide nicely, with no visible shading problems, but is there another way? Just feels like this isn't the best method of this kind of thing. Pic related is the result.
