While making a sharp left-hand turn heard a pop in the steering wheel and immediately the airbag lights turned on?

Can I ask if you had any steering components changed recently like a steering gear box/rack? If so, the clock spring can be wound up and break which sounds like what has happened. Here is how to change the clock spring out (spiral wire) which should fix the problem. Check out the images (below). Please upload pictures or videos in your response of any problems so we can see what to help you with.

Yep, there you go, the steering wheel can not be moved when the system is apart. The steering wheel will need to be removed to change the part out. Let me know if you need help with that.

Yes, the clock spring snapped. When you had the column off it must have turned and when it was reinstalled it was off enough that when you turned hard it snapped the internal ribbon. Before you take it apart be sure to rotate the wheel to the lock to the left and then to the right and then rotate it back to center. Now lock it in place at the steering shaft. Make sure the tires are straight and then make sure the wheel is straight. Now you can remove the wheel so you can get to the clock spring. Then be sure it is centered. The cable only has a small amount it can turn over the number of turns lock to lock.

Grab a scan tool and see what code is in the SRS system. It is not really possible to say what the issue is without the testing.
