School corrects FAFSA, wrong... in our favor

I know I’m resurrecting an old thread, but I’m wondering @Sweetbeet how this ended up, as I’m now in a similarish situation. I received notice yesterday that a change was made to the FAFSA by a school D applied to (but hasn’t heard from yet). I couldn’t find the change, so I called the FAFSA helpline and the person there told me the school and that they’d changed the amount we’d paid in taxes last year. That line was directly imported from the IRS, so it was disconcerting to say the least and the helpline guy advised me to follow up with the school. The first person I spoke to there thought it was very odd as well and tracked down which FA counselor made the actual change, but that person hasn’t returned my call or email request for an explanation. The change lowered our EFC by nearly $3000, so it would be a welcome change, but I don’t think it’s a correct change. We don’t even know if D will be admitted, and the EFC for this school was unrealistic in the first place, so I’m thinking at this point I just let it drop as in all likelihood it’s a moot point.
