In past years, when entering an amount in Box 7 (Social Security Tips) of the Form W-2 Worksheet, Box 4 (Social Security Tax Withheld) would automatically update to reflect the correct amount as reported on the W-2.  This year, box 4 is not updating the amount to reflect this.  Box 4 can be easily overriden to reflect the correct amount per the W-2, so remember to do that this year.
