What the actual fuck do i do

Alright, to get started with, my parents ARENT married but have their taxes filed as jointly for 2022. I DONT KNOW HOW TF??? (is that fraud? 😰) technically my dad is supposed to be "head of household". I asked my parentsand they said its the tax ppls fault for filing their taxes jointly
