So I applied to the UC’s for fall 2015 and I got into a few of them. While reviewing all my information like the provisional acceptance stuff I did not take a planned course for Spring 2015 that I put as planned and wanted to report it. However when I checked my UC app i realized that I did not put down summer 2013 quarter as enrolled when I enrolled and W’d from a class, and I didn’t put it there. What should I do?
You need to let them know. Being as the summer is, what, 1 W?, it should be fine. But let them know. Regarding the last class not taken, it will depend on whether it’s a major req, breadth, or some other stuff. Assuming you have plenty of units, and the class has no bearing on anything, it should be fine. But I just got called out for giving an opinion, even if I always (unless it’s obvious) tell ppl to contact admissions - because I’m not admissions. So, yeah, I’m not admissions. Contact them! 
It wasn’t an important class but I read every single thread on this and I don’t want them to assume I omitted it on purpose and ban me or whatever :-S :-S :-S .
