GST CREDIT NOTE QUERY.....,.

GST credit Rs.100000+18% GST on 28-08-2020 for FY year 2020-21 is correctly adjusted in the GSTR 3B, but not reported in the GSTR 1, Time limit for correction of FY 2020-21 is already expired (due date date of filing the annual return retun or September 2021 GSTR due date) , is any problem for this? we can correctly report such credit in GSTR 9?
