My taxes are not the same as last year, I have added deduction and such which have changed the about of my refund but it hasn't. How can I find out what's wrong?

Please provide some more information about what deduction you're trying to claim so we can suggest what might be off or check out our list of common questions about deductions: https://turbotax.community.intuit.ca/browse/credits
