Q. Is this part for assistance that has NOT been reported on my 1098-T?
A. Yes.
Q. I should just put $0 in the corresponding box, right?
A. Yes. Or better yet, answer no when asked if you got employer assistance (your employer is already treating it as scholarship).
The 1098-T is only an informational document. The numbers on it are not required to be entered onto your tax return. However receipt of a 1098-T frequently means you are either eligible for a tuition credit or possibly your student has taxable scholarship income. If box 5 equals or exceeds box 1, and you have no other qualified expenses (e.g. books), you don't need to even enter anything in the education section.
If you claim the tuition credit, you do need to report that you got one or that you qualify for an exception (the TurboTax interview will handle this)
You claim the tuition credit, or report scholarship income, based on your own financial records, not the 1098-T.
