If you are eligible to claim the Climate Action Incentive (CAI),
then you can go to the schedule 14 on your return and put the X in “Click this
box to claim the Climate Action Incentive on your return” to put it on your
return instead of your spouses.
If neither of you are eligible, then line 7 should already be
zero, since TurboTax will remove the credit if you are not eligible.
Also make sure that you copy of TurboTax CD/Download is updated:
