          "Tax-exempt interest income", did not provide respondent with any           
          clue that there was a potential controversy.  The inclusion of              
          the amounts on line 8b, indicating petitioner's position that the           
          amounts set forth were exempt under section 103, did not do the             
          job.  Identification of the correct section of the Code to                  
          support a reported position does not, without more, provide                 
          sufficient information to enable the Commissioner to identify the           
          potential controversy.  Elliott v. Commissioner, supra.                     
               For the foregoing reasons, we find that petitioner neither             
          had substantial authority nor provided adequate disclosure of his           
          position for the treatment of the items at issue.  Accordingly,             
          we hold petitioner liable for accuracy-related penalties for                
          substantial understatements of income tax under section 6662.               
               To reflect the foregoing,                                              
                                                  Decision will be entered            
                                             under Rule 155.
