Tds - challan and deductee remove

Sir,

We are filed 2014-15 - 26Q - Q2 TDS Return. We want remove Challan and Deductee details in TDS Return. Because we are paid TDS amount for Payment of TDS on Sale of Property (vide Form 26QB). We are wrongly mentioned in TDS 26Q Return. This amount is no need to metioned in regular TDS Return (26Q).

Now this challan amount is shown in Un-Matched Challan List.

1) How do remove this challan amount & Deductee record ?

2) We are unable to download conso file, due to Un-Matched challan is pending. How to rectify this problem?

3) How to file revised return?

Plz help me.

Regards,

M.Shanmugasundaram
