The kiddie tax is really a separate subject. You may want to post a new question to get experts on that subject to look at it. I'm not very knowledgeable on it.
That said, a cursory review of form 8615 shows no place to enter the parents capital gains/qualified dividends; only a box to check if the Qualified Dividends and Capital Gain Tax Worksheet was used.
If the student has capital gains and or qualified dividends, that will come up in the income interview.
