Ok. So just clarifying everything so far. I was claimed as dependent for 2019 and 2020. I could have been claimed for 2021 due to being under 24 years old in 2021 and full time college student for at least some part of 5 months of the year, and was provided more than one-half of support. So, this means I have to file an amended return? If I do so, would my mom be required to as well or only if she wants to? And when I amend, what interest and penalties are involved when paying it back? Does it increase my chances of being audited?
