How do i remove CWB? when I go to review, I am getting a warning that I am claiming CWB. I am not sure how I am claiming this and I do not want to claim it.

The Canada workers benefit is a refundable tax credit to help individuals and families who are working and earning a low income.

If you run the Review, you'll get a page asking "Do you want to claim the Canada workers benefit?", where you can say no if you don't want to claim the CWB.
