Why does TT show a much lower amount for "other withholdings" than my W-2 shows? Medicare, social security

Thank you! It finally clicked for me. I was incorrectly including the base taxes at 1.45% already paid when calculating how much I should owe. TT correctly picked up the surtax already paid (although was confusing as it labeled it as "other withholdings"), and the delta I owe is $1,350.
