I work and go to school fulltime. My parents got a 1095-A from Marketplace and I am also under this plan. We are a family of 4. How do I report this on my taxes?

I am filing my own taxes, am 21yo, my sister is 10yo and both my parents live in the household. My parents claim me, but in doing my taxes it is asking for 1095. Since i am on my parents' i don't know to do this math to figure out the correct numbers, but I did find out the SLCSP was $1,770.51. What's the premium percentage, my SLCSP percentage and the advanced payment of PTC percentage?
