Cannot file GSTR 3B as tran 1 is filed
please help I have submitted the GSTR-3B but I cannot file. Once I enter OTP for filing 3B, I get a message which says “You have SUBMITTED TRAN-1 form but have not FILED it. You are requested to FILE the same before submitting this return” I have already file TRAN – 1 form 20-12-2017 status - FILED showing. When I go to again file Tran 1, it shows The filing of declaration in TRAN-1 is not available now as the due date is over.
What shall I do now?
