Even though the parent may be using the 1098-T to claim the tuition credit, the student can still use the same 1098-T to report taxable scholarship. Do not try to enter taxable scholarship in the income section.
In TurboTax (TT), enter at:
Federal Taxes Tab (Personal for H&B version)
Deductions & Credits
-Scroll down to:
--Education
--Education Expenses and Scholarships (1098-T)
Continue even if TT tells you your not eligible.
Enter the 1098-T and follow the interview.
Enter the 1098-T, exactly as received, on the student's return. Enter book and computer expenses separately. In his interview, you should eventually reach a screen called "Amount used to calculate education credit" (or similar wording). Be sure the amount in that box is $4000. That will put all his excess scholarship as income on his return (line 8r of Schedule 1).
Be advised some people are saying they're not getting the "Amount used to claim the tuition credit" (or “Education Expenses used for a Tax Credit”) screen on the dependent’s interview. Check the student information work sheet (part VI, line 17) to verify it was entered. If not, the alternate workaround is to enter $4000 less than the actual box 1 amount, when you enter the 1098-T.
There's yet another (and simplest) work around. Manually calculate the taxable amount of scholarship and enter the 1098-T, on his return, with 0 in box 1 and the taxable amount in box 5. In that case the amount in the "Amount used to claim the tuition credit" box is 0 (if it comes up).
Before doing that, it may be helpful to first delete the previously entered 1098-T and start over, so that there's not conflicting data still hanging around
