Hit a Curb

Hey guys need a little advice. I have a 98 Camaro Z28. Last night I was making a U-turn and when I came out of the turn my car fish tailed. I tried to correct the turn and then my car fish tailed the opposite way. I ran my passenger side wheel up onto a curb. No visible damage can be seen but now when I drive my steering wheel is leaning to the left by about 20 degrees. In a straight line my car drives perfectly straight without my hands on it. No noises, no vibrations, just my steering wheel is off center. I jacked it up and cant see anything bent or leaking. Any ideas whats going on here. Is it just an alignment or did I mess something up in my gear box. I hit the curb at probably about 10-15mph.

Definitely need an alignment; they will be able to inspect to see if you bent anything like tie rods. If the steering is smooth turning left and right your rack is probably fine.
