Negative figure in table 14 gst payable gstr9

Credit notes and invoices dated March 2018 were entered in GSTR1 of April 2018 as they were missed out in March. The net tax effect was a 1200 GST on sales and 3000 GST on credit notes = -1800 which was adjusted against tax payable in GSTR3B of April.

For reporting in GSTR9,

Table 10 -  CGST Rs.1200, SGST Rs.1200

Table 11 - CGST Rs.300, SGST Rs.3000

How should I report this in Table 14? Because 1200-3000 is (-)1800. Negative figure.

What should I enter in tax payable column and tax paid of Table 14?

Thank you.

under table 14

Report 900/- under Sgst Payble & Paid

Report Nil under Cgst under Payable & Paid (ignore negative figures)

Yes, reported in GSTR3B before 31.03.2019. Thank you so much.
