Does my daughter have to pay tax on a tuition waiver for University if she works for it?

My daughter is going to University for her Masters has been given her a 1098T.  She has tuition waiver for work for them.  When she fills out her taxes on turbo tax, she has to pay tax on this ? and it is not waived.  Is this correct?  She entered the form into Turbo Tax and it is making her pay taxes on the scholarship.
