While preparing the profit and loss due to one wrong entry of accountant the taxable turnover exceeded the GSTR-3B Turnover.
This was a clerical error while passing entry of Purchase return Invoice value he passed sales return entry and hence the effect increased the turnover. In the transaction no tax involved.
The seller party has uploaded credit note in GSTR site and the Tax has been reversed in GSTR 3B
