Slot inside of counterbore

[jayreynolds5]

I am new to fusion (no training) and I cannot seem to find a way to mill the slot below. As you can see it is inside of a counter bore which then goes down to a flat on one side. it is a ball return hole on a ball screw. I feel this should be pretty simple and that I am probably just missing something. lease see the pics below and I appreciate any help.

So I actually got it right after this post with using a 2d Contour. I believe I was selecting my chain incorrectly.
