When you have two entangled photons, there is no such thing as amplitude of photon 1. There is only an amplitude for both photons together.

Yes, but in that case you are no longer considering two photons. And by the way, the expression "Feynman rules" means something entirely...

You could have explicitly pointed out that it should have been |Ψ|² = |α|²⟨A|A⟩ + |β|²⟨B|B⟩ + αβ*⟨B|A⟩ + α*β⟨A|B⟩ where ⟨A|A⟩, ⟨B|B⟩...
