I don't think you understand the question, so I will try to rephrase it:

Facts
1. MA (including the link you provided) states that MA will follow Fed (IE including the same AGI, IE the same 1/3rd of the distribution).
2. PTO doesn't reflect that, it does 1/3rd Fed and 100% MA because it calculates not from fed gross income in PTO, but rather via Sch XY.

Question

Why isn't PTO reflecting MA as it should?

Bonus Question

When will it?

The forms think you said to bookmark too isn't useful as it doesn't show anything other than when PTO updates 2020 from 2019, not when it updates 2020 to the latest provisions, for example, it mentions nothing about APTC recapture on the 1040. Also, it is linked from the PTO dashboard, so you don't need to bookmark it because it is one of the several quite useless links they provide for us by default.
