IGST wrongly shown as CGST-SGST

IGST wrongly split and declared in Cgst- Sgst column in gstr3B for 17-18. And the same not rectified till date. How to declare the same in gstr9 and which tables are affected?

for Eg. Actual amnt. as igst- 3000, cgst-2000, sgst- 2000.

wrongly as igst- 2000, cgst- 2500,
sgst- 2500. (in gstr3B)
(*Table 6A shows wrong figure as above. And Table 8A shows actual figure as above.*)

As per this eg. how to declare these figures in table6b, table 7, table 8b in gstr9 ? and declare any other tables required? and how ?

Any payment required to as reverse tax in Drc03 ( as per above eg. 500+500)?

plz reply by experts.
thanks.
