Taxable grants/scholarships are reported on line 1 of form 1040 with the notation SCH on the dotted line to the left of line 1. It's important that it be reported there as it affects the calculation of a student-dependent's standard deduction.
To get it there, in TurboTax (TT), it must be entered in the Deductions & Credits /Education / education expenses section of TT. Do no try to enter it in the income section.
If your scholarships exceeds your qualified expenses, TT will automatically calculate the taxable portion. But sometimes it's easier to use a work around. The simplest thing is change the box 1 and box 5 numbers at the 1098-T screen to force the result you want. Special handling is needed if you're forcing some of the scholarship to be taxable so that you can claim the education credit.
