I am on a "self only" HDP plan and she is on a "Self plus child" HDP plan. In this scenario, what would our combined maximum HSA contribution be for 2024?

"she" is my wife in this scenario.

The combined maximum HSA for your family for 2024 is $8,300, with an additional $1,000 if one of you is 55 or over.  

Please see this Publication 969  from the IRS: Rules for married people. If either spouse has family HDHP coverage, both spouses are treated as having family HDHP coverage. If each spouse has family coverage under a separate plan, the contribution limit for 2024 is $8,300.
