Difference inTRIAL Balance

Dear All,

I one of the Problem in TRIAL Balance.

The TRIAL Balance is coming with Difference of -18000.When i searched the Document i came to found a Single JV that was Passed and then Reversed which Includes TDS and in the Voucher Debit is Zero and Credit is 18000.

This Occurs due to data being changed by Back End by IT manager.

Now Kindly Suggest how i can solve this Issue because If i Pass any Entry to Knock off then again the Amount of 18000 will Reflect in Trail Balance.
