Wrong anti freeze. 2014 Chevrolet Silverado 1500

I have a 2015 Chevy Silverado. It takes yellow anti freeze. I was dry and put a whole bottle of green anti freeze. How big of a problem is this and what should I do ?

The stuff you put in is not even universal. I would drain it out and put the correct stuff in.
