Blank spaces on FASFA

@thumper1 My mom was being defensive about giving me all her tax information, so she only really gave me what the fafsa application asked upfront. Is it 100% certain that I will be asked for those tax transcripts. My main concern is that I already applied to a college and the fafsa deadline has passed. I don’t want any updates to delay any financial aid package I may receive if I update past the deadline. Is this an issue?
