Error in gst payment!!!

I have filled 4 return today 

there was no table to put the late fee amount.

so I filled it normally and the return got filed successfully. 

now the question arises is how this late fee will be paid if it is applicable?

pls help me out with this!!!

I know I can pay teh late fee by Creating Challan.

my point is just like in  3B - if we are filling the 3B return   late the system autometically calculate the late fee and it appeared in one of the table.

and if didnt pay the late fee by generating the challan the retun would not get submitted and filled

but in case of GSTR 1 - there is no such table where we can put the  late fee details and amount and even the syetem is not calculating the late fee automatically.

I have checked the Liability register and the cash register- No late fee amount or nothing like late fee outstanding showing

have you paid the Late fee by challan before filling the GSTR 1 today?

NO NEED TO PAY AS THERE IS NO OPTION TO PAY LATE FEE FOR GSTR 1 

late fee was paid for GST 3B and later on its waived off.
