There is no requirement to claim any or all of the available tuition, education and textbook tax credits in a particular year. However, the amount that can be carried forward is determined by a formula that appears on the Schedule 11 and does not depend on what the student chooses to claim.
Therefore, if a student chooses not to claim all or such portion of the available tuition, education and textbook tax credits required to reduce federal taxes payable to zero before claiming certain other tax credits (medical, charitable, interest on student loans, dividend tax credits and the foreign tax credit), the tuition, education and textbook tax credits not claimed cannot be carried forward and will be lost.
Generally, the carry-forward mechanism is designed to address the situation in which a student does not have sufficient tax owing against which to apply the available tuition, education and textbook tax credits available in a particular year..
All of this to say that you cannot choose yourself to report the amount of tuition credit unfortunately, This is the order in which non-refundable credits needs to be claimed and Tuition fees comes before other non-refundable credits.
