Either you can issue a debit note to nullify the effect but that will create difference between GSTR-1 & 3B in the current year without rectifying the difference of previous year.
You can amend the credit note and change all values to zero.
You can leave the situation as it is but show the correct position in annual return. Since you have already paid correct tax in GSTR-3B which is more there won't be any problem
