dear sir

i have manufactured goods in the month of December 2017 and take the ITC of IGST, CGST, SGST and filed my 3B 

the aforesaid goods sold without payment of tax through export in the month of January 2018 and also filed my return GSTR-1 with proper data like, invoice number, invoice amount, shipping bill number, shipping bill date, etc

now i want to file my refund application in form RFD-01, but in the form RFD-01 following formula available

current month input / current month total turnover x current month zero rated turnover = eligible ITC for refund

so in this situation my result in RFD-01 reflected as a "0" as i have no any ITC available in the month of Jan-2018

so please guide me how to file RFD-01 and get refund?

thanks
