GST annual return : FY 2018-19

The turnover of FY 2018-19 was 80 lacs but was filed as 82 lacs including 2 lacs of FY 2017-18. The same was shown in annual return of FY 2017-18 that 2 lacs turnover was reported in FY 2018-19 in table no. 10.

The query is, While filing the annual return of FY 2018-19. How this 2 lacs need to be treated as the 3B summary is showing as turnover of 82 lacs in this year whereas it is 80 lacs only. Is their some option in annual return of FY 2018-19 where data of FY 2017-18 can be reported.

Thanks & Regards
