How do I change my assessment I put the wrong numbers in one of the boxes

You can make changes to a filed tax return by filing an adjustment. The Canada Revenue Agency (CRA) requires that you wait until you’ve received your Notice of Assessment (NOA) before filing an adjustment. In many cases, the Canada Revenue Agency (CRA) will catch the mismatch and automatically adjust your return for you. 

There are three ways to make amendments to your tax return: through Canada Revenue Agency CRA My Account, ReFile using your tax solution, or by mail. There are rules and limitations for each one, please see the following link for their descriptions:
