Filed gstr-3b but trns-1 not yet filed

I have already filed GSTR - 3B on 18/8/17 and Status showing FILED

But TRNS-1 Not yet filed which introduced on 19/8/17

Now I am going to submit TRNS-1

Question: 1) Have any Rules to submit GSTR-3B and TRNS-1 Jointly ??? ( because GSTR-3B filed but TRNS-1 not filed)

                 2) Can Cenvat credit will  carry forward to Credit Register after submission of TRNS-1 ?? ( because  GST portal   showing  Credit Register of July is already fixed and showing opening balance of Aug)

Please reply............ thanks
