When I recommended that you speak with your financial aid office, we were talking about your mom having no income in 2016 explaining how you had money to come to the US.
You had not disclosed that your family had a small business before coming to the US.
You must put the income from that business on your FAFSA, it does it matter if the money was made in another country.
Yes, as @thumper1 stated, you must change your FAFSA to include your income from 2016, as right now you are a little less than truthful about your financial situation and it will come back to bite you- you could lose your admission at your school , not receive financial aid in the future and have to repay all aid that you received as a result of misrepresenting your fiancial situation
