FAFSA: Off or On Campus

Hello, I am going to be second year student at UC Berkeley, and I got a housing offer which I accepted to live on campus on UC Berkeley.

However, on my FAFSA, I was planning to live off campus because I thought that due to the lack of housing and lottery system at UC Berkeley, I would not be able to get housing for the 2018-2019 school year. I took the housing on the university because it would surprisingly cost less to live on campus rather than off campus.

Should I try to change my FAFSA application and resend it to the university again or does it not matter?

Thank you!
