If the income didn't belong to you and instead it was for a program, the issuer of the form should correct the 1099-MISC and issue it under the non-profit's name. If they won't fix the Form 1099-MISC even after you asked for a change, you can contact the IRS and file a complaint. You can call them at 800-829-1040 or set up an appointment to visit an IRS taxpayer assistance center (TAC).
