First remove the lower dash panel. It is connected to the center console, to the firewall, and near the fuse box door. You will need to do this to unplug the stalk’s pigtail, which is quite long.
The upper cover isn’t “removeable”, and it’s removal isn’t necessary. Stick your head in the footwell and look up to see the large flat head screws holding the lower cover in place. There are about 4 screws holding it in place.
From there you can access the two phillips screws holding the stalk to the upper column.
A snippet from another thread. The pic is looking at the underside of the column:
It's a misnomer to refer to the upper steering column cover as a "cover". It's an integral support of the steering column as well as the ignition cylinder.
Can you please let me know how to remove upper column cover and how do I remove horn part on steering wheel like this:
It depends on which wheel you have. If you actually have the sport wheel pictured, use a thin screwdriver to pry between the black horn pad and the chrome trim ring. There are three plastic screws that press into holes in the trim ring. The trim ring is actually metal on this wheel.
If you have a bus wheel with the buttons on the steering wheel, the horn pad is different. The chrome ring is integral to the horn pad. The same three plastic screws are there but you need to pry under the “chrome” piece. The trim ring is plastic on this wheel and it is glued to the foam horn pad.
