Can be report in table 5 of GSTr. 9 as it's does not have any Tax Implications.
Moreover U can also report in 10 or 11, in GSTR 9 , As the Total turnover in table. . 5Q of GSTR 9c is to be match from the total of 5N, 10,11 of GSTR 9. In table 9 of 9C is only a table where the bifurcation of Rate wise Turnover to be reported & which shall be be matched with table 9 of GSTR9 , so I don't understand where is the problem .
As above I have stated no need to report exempted supply .in table 10, Report it under 5 of GSTR 9 & Report Exempted sale in Table 7B of GSTR 9C , you will get net taxable supply in table 7F of GSTR 9c
