I went back and edited my post because that was incorrect. I used an online calculator and missed that it took out the standard deduction from the 120k. The effective rate would actually be 15.1% on 120k taxable income.I follow most of what you are saying, but can you explain the part I bolded? How are you getting that the effective rate is 10.62%? This past year, I changed our 401k deduction to all pre-tax instead of post tax trying to still be able to take some of the American Opportunities Credit for our DD in college. I am trying to decide whether to switch it back or leave it all pretax this year.
That was using 2019 tax brackets shown here:

So on 120k taxable income (note that's 120k after all deductions are taken) you would pay:
10% on $19,400=$1,940
12% on 78950-19401=$7,145.88
22% on 120,000-78951=$9,030.78
Total taxes due would be $18116.16. Divide that by 120,000 and you get 15.1%.
