Do I fill out Parent 2 information on common app even if I don't live with them?

My parents are divorced and when it asks about Parent 2 in common app I am wondering whether or not I need to fill that out. I can’t say I don’t have enough information because I am in contact with my second parent but I do not live with them.

I have a similar issue here. I live with my mom and stepdad, i see my father every once in awhile, I don’t think I have all the information that the common app wants for my father, but I definetely have it for my stepdad. Am I supposed to list my father or stepdad as parent 2? or neither? both? :-/
