Dear S Ramakrishnan Sir,

But if not diposited your Chalan in correct Section 94J Then firstly you have to change the Section of chalan to 94J by online Chalan correction prosizer for relevant Quarter, after 2 - 3 hours correction accepted of chalan correction, then you have to download conso file and conforme that chalan is matched, then set your party's entry against the modified chalan which now with correct section and revise your return threw NSDL.
