Mismatch in Gst Returns for the Month of March 2021

A user encountered a mismatch in their March 2021 GST returns because a debit note raised against a purchase was incorrectly shown in GSTR-1. The advice provided is that debit notes for sales should only be reported in GSTR-1. To rectify the error, the user can either amend the previous month's return by setting the debit note value to zero in the next month's GSTR-1 and GSTR-3B, or issue a credit note against the debit note in the subsequent month's filings.
