"The tax is for the earnings portion of the distribution."
You mean the taxable income amount is the same as the earnings portion? That usually indicates you haven't entered the educational expenses.
The interview is complicated. You have to carefully enter the expenses and answer the qualifying questions. That why I recommended that you not enter the 1099-Q at all, if you already know it's a qualified distribution.
If the student is not your dependent, the interview is usually a little easier. After entering the 1099-Q, several screens later, you will get a screen titled "Non-dependent student expenses". All expenses can be entered on this single screen. There are boxes for tuition, books, room & board, computers.
