Gst Annual Return

can be corrected in table 4 by increasing B2b sale & decreasing B2c sale & in table table 10, 11 of GSTr 9

I don't think it will effect in table 10 & 11 of GSTR9

Yes you are Correct ! it will not affect , but as the amendment for FY. .2017-18 is done in FY 2018-19 , hence required to report in 10, 11

Amendment in GSTR1 of 17-18 in 18-19 From B2c to B2b. No change in taxable value & in tax amount.No change in GSTR3B of 18-19 for this. where should I report in GSTR9.
