Mistake in GSTR - 3B filed. how to rectify

#1
When filing GSTR 3 B I taken ITC on Inward Supplies wrongly in Inward Supplies Liable to Reverse Charges and submitted and filed GSTR 3B. Actually I do not have any ITC liabilities on Reverse Charges. So please tell me wether my actual ITC on Inward supplies available for setoff in GST Final Returns (GSTR 2 & 3) for July 2017?
