Sir / Madam,

I have filed my GSTR 3B for January on 19.2.2018 (befit due date) and after that my client gave me some sales bills so these bills could not be taken in my GSTR 3B but on the due date itself i have made the payment of tax liability on these bills.
So what can be done of now of this?

Thanks in advance.
