Unused tuition fees are tracked by CRA and amounts are reported on your Notice of Assessment.
Amounts may be seen in My Account and are downloadable using AutoFill (AFR).
If you have unused Tuition, you can enter amounts under the Tuition section of 'Deductions'.
Amounts of unused credit are applied to reduce tax payable automatically. There is no option to voluntarily postpone the use of unused amounts. CRA knows your unused amount of tuition and they will apply for the credit even if you don't enter any amounts of carry forward yourself on your current return.
For directions on how to claim your tuition fees, here is a TurboTax FAQ link below.
