I use Tally software and I file quarterly GSTR1 returns. I have filed my GSTR 3B correctly for the months April, May & June 2018. But While filing my GSTR1 for June 2018, I missed all the invoices for the period April & May 2018, and only the invoices of june was exported from tally and filed for the Quarter ending June 2018.
I want to know how to include those Invoice for that periods GSTR 1? Now I have already filed my GSTR 1 for Quarter ending Apr 2019.
