since you both were or will be covered by a HDHP for all of 2024 - either can contribute up to the max or it can be split anyway you want. if either or both are over 55 there is a $1000 maximum catchup for each that is over that age, but it can only be contributed to the account of the person over 55 or up to $1000 to each account if both are over 55
the family max as you noted for 2024 is $8300
in turbotax when you do the HSA entries check for each HSA form that you were covered by a family HDHP for all of 2024
