How do I calculate NJ Tuition Deduction amount (New Jersey Institution of Higher Education Tuition)?How to account for scholarship and grant? Should the tuition deduction exclude the scholarship or grant?

I'm working on my tax return and my dependent has 20,000 in tuition and 15,000 in scholarships/grants. For the NJ Tuition Deduction purposes, should I claim the entire 20,000 or only 5,000 in tuition? Looked up all the information from the NJ Department of Taxation and found no guidance. Thanks in advance.
