GSTR 9 Annual Return

In GSTR9 FY 17-18 Annual Return, we filled 8C ITC which was availed in next financial year i,e FY 18-19 so GSTR2A match with GSTR 3B but in GSTR 9 FY 18-19 GSTR 3B included amount which was shown 8C in GSTR 9 annual return of  FY 17-18 and some amount availed in FY 19-20.......

for Example....

FY 17-18- GSTR 9 Table 8C shown Rs.1000

so my GSTR 2A - 2000 and my 3B Rs.1000 balance Rs.1000 availed in FY 18-19.

And My query is how to shown above in my GSTR 9 For FY 18-19.

My GSTR3B claimed Rs.1000-opening which was shown in FY 17-18 in Table 8C. + current year availed Rs.1000 -  Rs.1000 availed in FY 19-20.... = GSTR 2A Rs2000 but not able to split this in FY 18-19 Annual return

how to file GSTR 9 of above Opening ITC .....? opening +current year availed - availed in next financial year = 3B net ITC but how to file in GSTR 9?
