I got married in 2019, so I need to fill out form 8962 - and I am trying to calculate the  Alternative Calculation for Year of Marriage. I have all of the information needed for part V, but when I am filling in part II I don't know how to enter column C. For the months before we were married do I add column C from worksheet II and worksheet IV together? What number do I use for the months after we were married if I do not have an amount from line 8b? The healthcare was for our son so the alternative family size is the same for both of us.

Thank you in advance for the help!
