Mechanics online? I need help with 370Z

[D370z]

Couple weeks ago the car used to run just fine until one day it just wouldn't start, it could probably be because I turned the steering wheel while it wasn't running and broke the wheel lock or I dont know how that works, any ideas how to fix?
The car won't do anything except the light at the button where you start engine, and the yellow warning sign,
I tried to, replaced battery, checked fuses, moving steering wheel to left and right, I went to the dealer and they said that my car won't get signal from the stewing wheel and the the steering wheel angle sensor might be disconnected, I checked it isn't,
The wheel is currently in lock position and I'm stranded my car has been home for more than a month, no warranty on it.

Anyone have any ideas what could be the problem?
Thank you!
