Challan Correction with AO

Hello everyone one of my client has wrongly paid challan mentioning different AY instead of correct one. Actually it was pertaining to AY 21.22 but he has wrongly selected AY 20.21 against outstanding demand.

Now the actual problem is demand is still showing on E filling portal for the AY 21.22 but payment actually have been made. Also portal is not showing such Challan in payment history.

Now only one way is left to approach jurisdiction officer & to make a request for challan Correction to offset the liability


Is there any proper way or application format for doing soo if anyone can help it will be very helpful

Thanks in advance
