I'm trying to extrude the highlighted sketch through the thinner half ellipse at the center.
If I just revolve it, the result is too large. Thanks in advance.

Just to piggy back...How can I attach a file to a forum post?
How about revolving the half ellipse 180° about the axis of the main round portion (turn on view temp axes)?
And per Mr. Mather's suggestion, see: How can I attach a file to a forum post?
Why not a simple revolve along the axis of the main cylinder of a partial ellipse section?
You can also use the Dome feature and select Elliptical dome:
