Tds return

BY MISTAKE WHILE FILING ORIGINAL RETURN, I HAVE BOOKED A TDS ON RENT  OF NOV MONTH AGAINST A CHALLAN AND TDS ON RENT  OF DECEMBER MONTH IS ALSO BOOKED AGAINST SAME CHALLAN.

NOW IT RAISES DEMAND FOR DECEMBER MONTH TDS. I HAVE A SEPARATE CHALLAN FOR DEC MONTH.

HOW TO REVISE RETURN ONLINE.

I HAVE ADDED NEW CHALLAN TO STATEMENT NOW HOW TO ADD DEC MONTH TDS AGAINST THAT CHALLAN.
