Senior Deduction for Qualifying Surviving Spouse

I have a AGI of around 175,802 and am filing as a Qualifying Surviving Spouse. By my estimation the standard deduction for me should be as follows:

Base Standard Deduction (Qualifying Surviving Spouse)  - $31,500

Additional Deduction (For being 65 or older).                     + $1,600

New 2025 "Senior Bonus" Deduction (Phased out).            + $4,452

TOTAL STANDARD DEDUCTION                                              $37,552

The "Senior Bonus" Deduction: A new law for 2025 (the One Big Beautiful Bill Act) added a potential $6,000 bonus for seniors. However, for Qualifying Surviving Spouses, this bonus begins to phase out if your Modified AGI is over $150,000.

Since my AGI is $175,802, your bonus is reduced by roughly $1,548 ($0.06 for every dollar over $150k), leaving you with approximately $4,452.

why is turbo tax choosing my itemized deductions of $36,553 instead of the $37,552? How can i check the standard deduction calculation?
