FAFSA changes for divorced parents 2023-24

The gap is where the financial aid comes in.
This is September of her senior year in high school. She’s made no applications, doesn’t know if she’s going to be accepted and doesn’t know what her financial aid package will be.
I’m not sure why people are talking to me like I’m an idiot for assuming she’ll get more financial aid using her mother’s $28k a year income versus our $245k.
There are a ton of unknowns, I’m just trying to determine if there’s anything we need to do now to help us in 2 years in case she decides to go there. We will need to use our 2021 taxes for that, and 2021 is almost over.
