I made a mistake on my application...and I already applied

I go to a school that lets me take college-credit classes at the nearby community college. I signed up for a fall class, so when the Rutgers application asked for the colleges I had attended, I put the name of the community college. However, I forgot that this was just a fall course, so I had it go from September 2016 to May 2017 instead of September 2016 to December 2016. I only realized this mistake after submitting my application. I am getting really paranoid and I want to know whether this will hurt my application.
