Wrong payment of cgst and sgst in gstr3b?

Dear Colleagues,

While filing the return of gstr 3b for the month June 2018, In one of the invoices, instead of claiming IGST and paying it, by mistake cgst and sgst were claimed and paid into account and the return was submitted and filed. Actually we should have paid under IGST. Now how to correct this problem? Please guide me.

Have to file GSTR1 as well. So while uploading the invoice details of B2B, there will be a contradiction of inter-state GSTIN of service recepient and CGST,SGST amout in invoice instead of IGST.

Thanks.

Aravind.
