  If the child lived with you, you are the custodial parent. The question is answered, above.

 

But what are the other details? You say "She is currently in college".  Does that mean she lived with her mother, but now lives with you only because you're closer to the college? That could be considered a temporary absence and her mother is still the custodial parent.
