Gstr 9 2a negative figure

A user is experiencing an issue where a figure in GSTR 9, point 8, has become negative. This is due to a supplier filing a late return for sales made in February 2019, which was initially reflected in the March 2019 GSTR 2A. The advice given is to file the return with the difference in table 8D and be prepared to provide original bills, GRs, and the supplier's GST returns if a notice is received.
