In August 2021 I have added 4 B2B invoices in IFF/GSTR1 and filed the same. As it was in QRMP I filed the 3b in Sep 21 quarter but I could not add the invoices in gstr 1 as it was telling that the invoices already exist. then I filed the GSTR 1 without any B2B invoices.
and then I filed the 3b of Sep 21. but the party portal shows the 3b filing status " N " now what should I do.
Now I am in monthly return mode after Sep 21 Q.
