I have read through this problem and tried all of the hints and tips mentioned. Ensuring that I did answer yes I was covered by HDHP during 2019...
I am eligible for $4500 HSA deduction
I contributed $3375 for 9 months of the year before I had employment
I had the remaining $1125 withheld from my W2 paycheck by my new employer.
Form 8889 is not including the W2 Box W amount of $1125. It is only allowing the $3375 that I deposited into HSA account prior to employer based W2 withholding. So I am missing out on $1125 income reduction.
Hopefully this is enough information for you to track the bug down. I am unable to file my taxes correctly using Turbo Tax as I am denied the remaining $1125 deduction.
