Reg gstr3b return for july 17

Dear All..

Good morning. This is regarding GSTR3B Return for July.

While filing GSTR 3B today morning unfortunately missed to enter the eligible ITC. But entered the output details correctly and also submitted the same. 

While filling payment of tax details, i realised that i have missed to enter the ITC details. Now its shows error for offset the liability.

Although my liability is more then the input credit. I.e., liability is 1.5 lakhs and the input credit is 98000 only. Anyway i have to pay the balance of 52000 as cash. So not able to file gstr 3b.

Now my question is can i need to file GSTR 3b for July or else can i left GSTR 3b as it has and proceed for filing GSTR 1 directly. 

Or

Anyway i have to file GSTR3B. If so pls guide me how to file the return by offset the liability.

Pls do the needful.

Thanks in advance
