How to change period in PT challan

Dear all,

I have taken PT number in the month of September and chose the effective date as 1/4/23. In the month of September I have made lump sum payment of PT from Apr till Sep along with late fee and interest as I made payment after September but the period selected was from 1/9/23 instead of 1/4/23 till 30/9/23. 
How can I rectify this, is there any way because the client has already paid lumpsum amount now he will not pay again for the same months.

Please help me it is urgent.

TIA
