I think we can not have equilibrium constant to Ka here. some kind of typo is there or information is missing here.
This buffer is made by adding salt of weak base to it.
thus,
base huge excess limited quantity of OH-
excess
NH4+ is excess from above reaction as well as from NH4Cl.
now NH4+ is WEAKLY acidic and if you consider Ka here, it will be
So, there is no way to see K = Ka correlation here.
