Amendment to gstr 1 for previous year

Can GSTR 1 be amended in the B2B section for the month of february 2018 as on today's date? Actually GSTR 3B for the month was filed correctly and the amount was also paid correctly. But the invoice uploaded in GSTR 1 was for the month of Jan 2018 instead of Feb 2018 by mistake.Which was already uploaded and filed. Are there any measures that can be taken to rectify this mistake?
