If your child was a full time student for part of at least 5 months (Jan-May), then she is still a full time student for dependent status.
If she "lives at home" for more than half the year, then she could still qualify as a dependent. When a child is away at college, they are usually considered to "live at home" because college is a temporary absence and the child can still be expected to return home for vacations, summer break, etc. But if the child has permanently moved out and established a new home, then they don't live at home any more, and if they lived "at home" less than half they year, they don't qualify as a dependent.
If she was a full time student for 5 months AND can still be considered to live at home, then you have to think about the support test. But if she doesn't pass the student or live at home test, you don't have to calculate support because she doesn't qualify on other grounds.
