Effective January 1, 2017, the federal education and textbook tax credits were eliminated. This measure did not eliminate the tuition tax credit, and it does not affect the ability to carry forward unused education and textbook credit amounts from years prior to 2017.  When you enter your carry forward amounts, TurboTax will automatically use as much of your credits as necessary to reduce your federal and provincial net tax owing.  You may want to contact the Canada Revenue Agency to verify the amount of unused tuition credits that you have available.  The Canada Revenue Agency can be reached at 1 800 959 8281.
