I created this body using the approach [this user](https://discourse.shapr3d.com/t/how-can-i-subtract-a-sketch-around-a-body/23276/8) suggested. Now I’m trying to subtract/extrude the section highlighted below but the body is tapered.

Which tool can I use to achieve this?

Can we assume the extrusion you wish to subtract also has a tapered edge or feature? All we can see is a highlighted surface.

One way is to simply re-create the original tapered body minus the area you now wish to subtract.

In this picture, you have the “offset face” tool selected. Did you select the “Extrude” tool?
