If you were only on assistance and went to school- they may have included the Canada's Workers Benefit- which if you didn't work and went to school would not be entitled to. Do you have children, and are you claiming anything else?
Please review where you entered your T-Slips- making sure you entered the proper amounts in the right boxes. You should have one from social assistance, one from your school- Did you receive OSAP? if yes, you do not enter that on your income tax return.
Thank you for choosing TurboTax.
