Can anybody help me to resolve overbooked tds challan issue. I have erroneously booked two different challans of Rs.93,000/- & Rs.40500/- each with same CIN no.123 while filing tds return of 24Q2 of F.Y.2017-18. This CIN no belongs to Rs.93,000/- and not of Rs.40500/-. Because of this I have got default notice with demand of Rs.40500/- and interest thereon because of overbooked challans. Now how to resolve this issue. TDSCPS customer care are saying that either I have to pay the said amount again or make the overbooked challan zero. I do not know how to do this.
