Finally figured it out with a lot of trial and error. You need to check the box under the Provincial Tax Credits that says "NEW! Climate Action Incentive (CAI) federal credit available for residents of Alberta". If this is not checked, you will not have the option to say who is claiming the credit. On the next pages you will be able to select options to say who will claim the credit. I was making the mistake of un-checking this box thinking it would remove the credit. It needs to be selected to pick the options. Hope this helps others.
