How can I take off the climate action incentive? I have tried starting a completely new return and it automatically added it again. Please offer me another solution.

In order not to claim the CAI you will go to the "Provincial" section and keep the CAI checked off then continue and once it asks you questions about the CAI answer them and once it says you qualify you will continue and then will ask who is going to claim this credit click on the name of the person and you will notice then the amount of your return will lower.
