During F.Y. 2018-19, I have deposited CGS+SGST instead of IGST. In GSTR1 also filed One Bills as CGST+SGST instead of IGST. How to rectify it?

You can pay the correct taxes now and go for the refund for the improper taxes paid. Further, as the invoice is relating to 2018-19, you can amend the same in your subsequent GSTR-1 return.
