I need some help with a stupid error

[Bearcat45]

So I was driving down the highway and had a brain-fart and decided to turn the key of my car (turning it off) instead of my wipers. I let the car coast and waited to come to a complete stop until I put the car in Park and restarted it. It seems to be driving well and everything but the engine light did come on. So naturally I am pretty worried and was wondering if i could get some help here before taking it to a shop. My car is a 2011 Chevy Aveo LT.

Thanks!
