GSTR1 Table 12.

This discussion addresses a user's query about forgetting to provide the HSN summary in their GSTR1 return for November 2021. While there's no direct option to amend this specific detail in GSTR1, it's suggested that the missing HSN summary can be reported in the GSTR9 annual return. An alternative mentioned is to include the previous month's HSN details in the current month's filing, though this requires clarification.
