Annual return

Your query it seems that you have failed to file GSTR-1 while you filed all 3B, or may be you have filed nil GSTR-1. Please clear you query first.

You could have made amendments in September 2018 or March 2019. But now you can edit the sales auto populated in GSTR-9. Since you have filed your GSTR-1 without taken then GSTR-9 will reflect nil since it takes into account only as per GSTR-1. But you can edit the sales. this way you can show the full sales and the positive thing is that you have paid tax in 3B as per you. Editing the sales as per GSTR-3B in GSTR-9 would at least be useful for you to satisfy tax authorities as and when they seek answers for difference in sales shown as per 3B and 1.
