Q. When filling out the scholarship/grants section, do I include any amount in the "Employer assistance" box?
A. Yes, but only the $5250 tax free part. Do not enter the taxed $14750.
You say "I was reimbursed for my tuition in 2024, $14750 taxed." And that is the correct way. By law your employer can only give you $5250 tax free.
But then you say "On my W-2, none of the tuition reimbursement was included in my income." That's not correct. Your employer is required to include the $14750 in box 1 of your W-2. You need to talk to your employer about what's going on. Most likely, it is included, and you're just misreading it. There is not a separate entry for the $14750 anywhere else on the W-2*. It's just included in the box 1 amount.
*Sometimes there's a notation in box 14 or (less often) in box 12. But even then, the amount is still included in box 1.
