I have no idea what you are talking about. Did you read what I wrote? The things you mentioned have nothing to do with populating 5805 Part II line 5. I think I explained the issue clearly before but let's try again.
Part II line 5 asks for THE TAX SHOWN ON YOUR 2018 RETURN. If your income is over $150,000 the amount should be 110% of the tax on your 2018 return.
Instead it is giving 90% of the tax owed on the 2019 return.
I have no idea what you are reading, but it has nothing to do with 5805 Part II line 5.
