QBI Deduction calculation for estimated tax not working properly

I am trying to let turbo tax calculate my estimated taxes for 2023, but I cannot figure out how it is calculating the QBI deduction. Here is the scenario:

 

Married filing jointly

Business is a SSBT

Schedule C income = $334,535

1/2 of SE tax = $14,412

Self Employed healthcare premium deduction = $26,640

Standard deduction for 2023 is $27,700

QBI deduction should equal $53,157 ((334,535 - 14,412- 26,640-27700)*.20)

 

But turbo tax is calculating QBI deduction amount to be $63,000. If the schedule C income amount is changed to $334,534 it calculates correctly.  Not sure if there is something I am missing on how it is being calculated.
