KrisD15 is correct, you do not need to enter either the 1099-Q or the 1098-T on either your return or your student's return. Your son is not eligible for a credit because he is a dependent. He does not need to enter the 1099-Q because you have already determined that none of it is taxable.
Entering those things will have no effect on either return. But. you run the risk of making an error in what is a complicated process to get to the answer you already know.
