Locked ignition and steering wheel

This has never happened before, but today I started my car no problems drove and dropped my mom off at work, then I made my way down to Walmart. When I tried to start my car the ignition was locked, so I wiggled the steering wheel back and forth and tapped on the brakes and tried to turn the key and it barely turned and it started up. I drive off about two miles stop at the gas station to get gas, well I try to start the car, well the ignition is stuck again so I tried to wiggle the steering wheel and press the brake, the steering wheel locked up and I didn't manage to get the key to turn, I tried moving the gear shifter a little bit, tried tapping the key in the ignition. I do not know what to do.
