Once you file a return in Zoho Books or file a return in the GST portal and mark it as filed in Zoho Books, you will not be able to edit the transactions included in that return. To make changes to the transactions, you will have to unfile the GSTR 1 return to make changes to sales transactions and open GSTR 2 to make changes to purchase transactions.
To unfile GSTR 1:
Notes: You will be able to edit the transactions only if you have not pushed the transactions for e-invoicing.
To mark the GSTR 2 as open:
Notes: Any changes you make to transactions after unfiling your GSTR-1 return should be manually amended when you file your future returns.
Notes: If you need to unfile/mark a return as open that is not the recent one, you need to unfile/mark the return as open from the most recent filing in reverse sequential order until you reach the return you want to unfile/mark as open.
