After you file

To remove Climate Action Incentive- You will go to the "Provincial" section of your return and once there, the first page will have a list where you can check off what you'd like to claim. TurboTax automatically will claim it for you- but once you get to the provincial section you can make sure that you do not check off "Climate Action Incentive" federal credit available. Continue and it should not give you the credit. Once you continue and get to the review- it will advise that you qualify but you can skip that warning and keep completing your return. 
Thank you choosing TurboTax.
