Hello guys I need help so I’m currently a senior in Highschool and we start filling out our FASFa forms October 1st well that’s when they open to begin filling out them

Well my mom isn’t the greatest

She doesn’t actually want the best for me

I asked her for the forms and told her before hand that in October I will need to begin to fill out the forms so today she told me she didn’t know where they were and she would have to make an appointment

Well I found some papers but it’s from 2017 and the school says it has to be based on 2018 tax returns can I use 2017 tax returns if she doesn’t give them to me or cooperate?

It also has her signature that was dated for 2018

So I’m quite confused

Please someone respond because I’m stressed the hell out .
