CSS and IDOC

Hello, I have recently sent in my CSS profile and am now starting the IDOC submission. However, i noticed that i reported my (the student) income received wrong on the CSS page as i stated that i made $690 in 2015 when in reality i made $0 in 2015 and the $690 made was my 2016 income so far. I know that I don’t have a tax form to submit, so I was wondering if I should say in the Student’s non-tax filer’s statement that the amount made was 0 and write in the source of income the mistake I made on my CSS profile or is the non- tax filer’s statement not the place to say the mistake i made? Thanks!

bump- not sure what to do with mistake on css in relation to idoc.
