Parents claimed me

I am 19 years old, working full time, and a full time online student. My parents claimed me on their taxes this year even though I feel like I pay for more than half of my own needs. I live in their house but I pay for my car insurance, my gas, my own groceries, my own phone and internet, even my own laundry goods. They do not have a house payment, only yearly property taxes, electric, and water. electric and water together don't cost anymore than $400 combined. They don't pay for health insurance as its free through the state. I bring in $4,000 a month and pay for all of my bills entirely on my own and even lending them money from time to time. They claimed me as a dependent but did not claim my income. I changed my settings last year to take extra money out for state taxes and I claim zero. From my understanding, this means I cannot file as independent and will most likely end up owing money like I did the year before as well. I received my W2 late in the mail so my parents were able to file before me. Is there anyway for me to file as independent and not get rejected? If my parents got extra money for claiming me, they are not going to send any of it my way and they will not be willing to file an amendment on their taxes.
