We returned some old stock(stock in hand before 1st July) to the seller in this(september) month for which the seller is going to issue a credit note after the calculation. Do we need to enter this detail in GSTR-3b as of now for the month of sept or it's not needed for old stock(before 1st july)?

If we need to enter please suggest how to enter the same in 3b.
