I entered in total tuition fees for 2018, as well as that I was in full time studies for 8 months. Why is it not getting added to my provincial tuition tax credits?

What's your province of residence?

Ontario! I just realized that the Ontario tuition tax credits were ended in 2017, so that was likely why. However, they also were not added for before September 2017, which they should have been (for those paid before September). I am going to have to ReFile for 2017.
