@Mike9241 My employer pays for the short-term disability coverage. The W-2 has an amount in Box 1, and Box 13 is checked (under "3rd party sick pay"). Tax was withheld per Boxes 2-6. The addition of this W-2 on the amended return was what showed an overpayment of my individual Social Security Tax Withholding, which is why I am now owed money back from the IRS. Best next step? Thanks for your help!
