@BabaBC It's no clear what's going on. Your original post didn't mention any "additional scholarship". Or are you now calling the tuition remission additional scholarship. Any scholarship in box 5, over and above the tuition remission, would be taxable unless you had additional expenses to enter, e.g. books and a computer.
If the school is putting the tuition remission in box 5, but leaving box 1 blank, that would be highly unusual.
