got notice for outstandin demand.
on verification - found that the demand is due to tax credit mismatch - and the mismatch is due to mistake in mentionig TAN No.
to correct this I logged in to the site > under my account > tax credit mismatch.
here the menu asked for latest communication reference no.
as I do not have for one year and for anohter I mentioned the intimation sent U/s 143(1) did not match - I opted e-NIRVAN menu.
grievance details entered form 26AS uploaded.
