UC App updating info

I just submitted my uc application, but did not realize that the parent employment and income section was still blank, is there a way to add this information after submission and will this affect my chances or scholarship eligibility?

Also, when paying for the application, there was a section to check if you were eligible for a fee waiver, and I entered a very rough estimate of my household income, and it just said “fee waiver approved” without any option to change the income. Is there a way to remove or update the fee waiver?
