Thank you for that clarification. You may have a refund offset. Please see this Help Article for more information regarding refund offsets.
You will need to contact the IRS regarding your refund being less than expected. 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.
