When the Canada Revenue Agency (CRA) asks for a certain line from your return, it is a security check to see if you are the person you say you are and have the availability to view your return. Make sure you are looking at the correct year of return and enter the amount you see exactly beside the line number they are requesting. It will always be a different line which will be used for verification. Also make sure to only include what they are asking for ie: with decimal or cents included or not.
