One Person has both Salary Income and Income from Professional services fees. He had forgotten the Professional Services fees received once only in last FY as he is not a regular service provider but a Service holder and it was not in AIS when he filed the ITR.
He filed ITR-1 instead of ITR-4. He came to know the Income from Professional Services fees from AIS, which was included at the end of August. Now his ITR has been processed but they are not refunding his due. Kindly advise.
