Interest on late paymentsm of tax

This discussion addresses a query regarding the calculation period for interest on late payment of RCM (Reverse Charge Mechanism) liability. The user paid an October 2019 liability in June 2020 and received TDS credit in April 2020. Advice suggests waiting for official notifications as there's a possibility of an interest waiver. Clarification was sought on the aggregate turnover and the GSTR-3B filing month for the RCM liability.
