FAFSA EFC

We’re a family of 5, and I would be the second kid in the family going into college. No child support, and the 41,000 is based off of our AGI. All the information was transferred from the IRS, but it just seems high because last year when my brother filed for FAFSA, his number was less than 1000. Seems odd, but not much I can do at this point.
