Could you clarify why you want to remove them? If it's because you wish to claim the CWB instead, you do not have to claim your tuition but at the same time you cannot claim the Canada Workers Benefit (CWB) as a full-time student. You will benefit from claiming your tuition when it is used to reduce your taxes in future years when your income is higher.
What is happening is your tax return was originally showing a refund of the Canada Workers Benefit (CWB) that full-time students are not eligible for. As soon as you enter your T2202A, the credit is removed and your refund is reduced.
Based on your employment earnings the software calculates your entitlement to the CWB, however, the government disallows this benefit to students. So entering the T2202 Tuition Certificate slip causes a recalculation and removal of this amount from the refund.
More information on the CWB can be found here: Canada Workers Benefit (Working Income Tax Benefit before 2019).
Thank you for choosing TurboTax.
Thank you very much, that makes sense, What I mean by remove is when I come to the "Automatically fill in part of your return" section on Turbotax there is a little garbage can that appears beside
Federal Tuition, Education and Textbook Amounts, T2202 - Tuition And Enrolment Certificate UNIVERSITY OF BRITISH COLUMBIA, and Provincial Tuition, Education and Textbook Amounts. If I press the garbage can button then my tax return value goes up quite a bit as you said it would. Thank you for the explanation
