Your Tuition Amounts will be used to "reduce your tax payable to zero". If your tax payable is "reduced to zero" but you have had NO TAX WITHHELD, there is no refund available. Rest assured that TurboTax will use your tuition "if needed" and carry the rest forward. And CRA will apply your tuition automatically when needed. They do not "recommend" you to use it if you owe....they APPLY it as soon as it is needed.
