If you've incorrectly entered a GSTIN in your GSTR1 return, you can correct it using the B2B amendment section. This process allows you to revise the details, including the GSTIN, by providing the original invoice number and date. This method is applicable even if you don't see a direct edit option in the current period's return.

You can amend the GSTIN in the B2B amendment section. It will ask for revised invoice no. You can give the same original invoice no. and date.
