How to edit css profile after you have sent it?

I have this issue, I asked my parent about the current year’s income and wrote down a particular number, now today my parent got the documentation about his/her income and it’s WAYYYYYY off the sum I indicated. What should I do? Thank you very much for your attention.

Different schools will have different procedures for updates. You need to follow the instructions for each school, either on their finaid web pages or what they tell you to do. Some will simply update the income numbers when the final fafsa update is done(after taxes are filed). Some want pen and ink changes on a paper printout of the profile. Some will require you to send tax forms, W-2s, 1099s etc., either sent to them directly or through the IDOC service. You need to find and follow the directions for each school.
