2019 MFJ taxable is $166,414.  Proseries says federal tax is $27,288.

But calculating myself (based on tax brackets) I come up with $28,327.

The Fiirst $19,400 is taxed at 10%= $1,940

$59,549 taxed at 12% = $7,145.88

$87,463 taxed at 22%= $19,241.86

Why is proseries calculation different than mine?  What am I missing?
