Why is "unused tuition and education amounts from previous years" coming up?

[TurboTaxAniqua]

Do you have any unclaimed tuition amounts from previous years? Carry forward unused tuition and education amounts from previous years. If you have unused education tax credits, you can carry them forward to help reduce taxes you'll owe in future years. Each year when you file your income tax return, first you'll use credits that were previously carried forward.
