For anyone at intuit who can fix it, or anyone else who is searching this, it appears to be a bug in turbotax's math.
Turbotax's 2021 Schedule H line 7 (federal income tax withheld) is drawing from our W3 line 2 (federal income tax withheld), plus line 4 (SS tax withheld), and line 6 (Medicare tax withheld).
Schedule H line 7 (federal income tax withheld) should only list the $ reported in W3 line 2 (federal income tax withheld).
