Is turbotax slightly off using 2022 tax tables?

on my “Qualified Dividend and Cap Gain Tax Worksheet”, line 5 (ord inc) is 35309. 

From 2022 tax tables  tax on ord inc should be 4032 = 1027.5 + 12% (35309-10275).

But line 22 of the worksheet shows 4034 ?  Only 2 difference, but why?  computation should be 4031.58, rounds to 4032, not 4034.

 - the Tax Smart Worksheet  has line 4 checked (Qual Div & Cap Gain Tax Worksheet)

 - there does not seem to be any way to see how turbotax is actually computing (tables imbedded?)
