Applying one year after finishing high school

Hi!
I am an international student and I am applying for colleges for fall 2016. But I graduated from high school last year on december. This year besides preparing my college applications I have been doing what would be the application to a university in my hometown, that takes a year.
Should I put this in the additional information section of the common app? Will it hurt my application if I dont?
It is the only thing I have left :slight_smile:
