If you haven’t submitted Form 7004 yourself, it’s possible that  

• your CPA,  
• staff member, or  
• A colleague may have filed the extension on your behalf. 

Additionally, you may consider contacting the IRS directly for more specific details about any previous submission or the reason for a possible rejection by calling 1-800-829-1040, available Monday through Friday from 7 AM to 7 PM (local time).
