My vendor has issued me 5 credit notes in October, which was not known to me until I saw it in the GSTR 2A for October. These credit notes were associated with bills it gave me in the month of September.

What should I do now? Where should I show these credit notes? I have already filed 3B till Feb 2018 without these credit notes. ANd I hv filed GSTR 1 till October.

I am confused as to where these credit notes need to be shown? Plz Help.
