Wrong pan number quoted in 26q return

I have quoted wrong PAN number in 26Q return of one party. I have now received notice from IT for payment of penalty for short deduction. What should I do? Can i file revised return with corrected PAN number or I have to pay penalty as per demanded by IT department. i have quoted PAN number of different party i.e whole PAN number is wrong. If i filed revised return with corrected PAN number then default penalty will write off by IT depatment?
