Form 5695 joint occupancy does not work

Form 5695 energy credit with regard to joint occupancy (other than spouse) still does not work right, even after the latest updates 2/24/2024.  For gas and electric heat pumps, the limit is $2000.  I split the cost with a joint owner, so my credit should be $1000.  If I use the joint occupant worksheet, Turbo Tax comes up with a credit of $250.  I know this is wrong.  The worksheet STILL does not work.  Has anybody else come to the same conclusion? 

 

The support sucks.  I can't ask a simple email question that can be answered definitively.
