Can I still use my graduate retention program credit if I don't have any tuition carry over amounts?

My Notice of assessment says, I Can use 2000 on this year's return. But when I try to enter into turboturx, it makes me add eligible tuition amounts in order to use the credit. But I don't have any tuition amounts for this year. And I don't have any to carry forward. Does that mean I do not still get to use? Graduate retention credit.
