I have submit the Form 3B, After submission of the Form 3B that my libilities increased. I gone through the report i realised that my purchase input wrongly feeded in the reverse charges (RCM) table. In short my purchase input as calculated as liability. Without payment of liabilty i can't file the return. Now How could rectified the mistake. When, I filed GSTR1 and GSTR2, It may credited in my account for my purchase input. The payment made by me to be credited in Cash Ledger.
While filling GSTR-3B, by oversight same got submitted instead of saving. Thereafter we have saved the payment challan for the due amount. However, we are not able to generate the challan for making the due payment. Message appears on the screen "oops system error" and we are not able to generate the challan and not able to pay the amount. Please let us knwo any solution for the above.
