Did a search and found a lot of topics on noises in our cars, but none specific to the driver airbag in the steering wheel. It buzzes when I go over rougher surfaces and if I press down lightly towards the floor (not like pressing the horn), the buzz goes away. Anyone else have this issue? any fixes?

I also have a buzz from the driver side a pillar, sounds like its coming from the tweeter area. The strut braces were checked/tightened, but that did not fix it. I'm thinking I'll need to take the door panel off and snoop around.

It might be that you have a bee or a fly stuck there, and it is making a buzzing noise.

Check if any of those noise is coming from the little buttons in the head of a turn signal switch.

I had that issue but the dealer fixed it about a year ago. I placed my hand on those switches and the buzzing still happens, place my had on the air bag/horn and it stops

You may want to dismount the airbag and see if there is an obvious reason visible for buzzing.

Dismounting the airbag is quite easy:
1) Disconnect the battery negative pole
2) Let the system drain for 10-15 mins
3) Put a screwdriver in hole under the steering wheel and push a metal wire to unclip the airbag
4) Help with your other hand and take the airbag unit off
5) Disconnect wire connections if needed
6) Check for rattling items

Putting everything back is doing everything vice versa.
