Annual return gstr 9 plz help

if credit is absolutely wrong taken in 2017-18 ,then you have to reverse the same and pay it in DRC 03 in cash with Interest .

What if. There is less itc in 2A but i have claimed more in. 3B and i have the proper invoice for the ITC WHICH I HAVE CLAIMED... BUT MY CREDITOR HAS NOT SHOWN IN HIS GSTR 1.

No worries..
If you fulfill all the conditions specified in section 16 of cgst act then you are eligible to take it even it is not showing in 2a.

And as you mentioned you have proper invoice, you are eligible for that ITC.
