Unsure of what? Colleges are a business. If they just handed out aid when in fact there are parents with money who just refused to fill out the forms, they would go out of business in a hurry.
You need to confirm with each college whether they need an NCP form or if you need to file a waiver. Don’t wait until they come to you. Almost every CSS profile school does. A few schools have their own forms. Check the websites, and call the FA office if you aren’t sure.
