You may not need to amend.
You can just not report the 1099-Q, at all, if your
student-beneficiary has sufficient educational expenses, including room &
board (even if he lives at home) to cover the distribution. When the box 1 amount on form 1099-Q is fully
covered by expenses, TurboTax will enter nothing about the 1099-Q on the actual
tax forms, including form 1040X (amendment).
