FASFA student income before 18

Thank you for your help. This FASFA thing makes me want to cry. My dad has a short fuse and about ready to tell me to shove the FASFA up my @$$ :disappointed_relieved:. I need to hurry up and get through this. So I never filed taxes last year because of my age and was told the threashhold was $12,000 for single under 65 🤷.
