Error on my application, already admitted

I recently was admitted at Sacramento State for spring 2018 and I have already submitted my intent to enroll. As I was adding the school in my fafsa application, the income seemed different. I looked at my old application and saw that instead of putting my income from 2015, I put the income I received for 2016, which is $9000 less. Will this cause for my admission to be rescinded? I wasn’t being dishonest. I read it wrong due to nerves. I’m really worried about my admission being revoked because of this stupid mistake.
