If your tax return does not have any dependents listed yet the IRS is saying the dependent information was wrong, you will need to continue to contact the IRS and follow any other instructions (if any) provided in their notice.
Please see How do I contact the Internal Revenue Service (IRS)? for more information, including the IRS phone number and hours of operation. You may want to try calling right when they open since they have been very busy throughout the day.
