Healthcare premium deduction for self-employed and ACA subsidy

[Krnrpkt]

Scenario: wife is self-employed and receiving healthcare ACA premium subsidy. I, husband, receive healthcare through Medicare and Medigap supplement. We file jointly. Using 2024 turbotax deluxe download, i do not see how/where to enter our combined healthcare premium total and link that to my wife’s business. It appears that only her information (i.e. premiums) as per the 1095-A are used to calculate the self-employed healthcare deduction entered on Schedule 1.
