Why use igst instead of sgst and cgst

1. where to show supply to other states and what is IGST? ( i am from west bengal) 

2. I have purchased item from a registered seller who has only filed gstr 1 till now but not 3b . I file on a monthly basis so the transaction was showing but ITC was not available . I have put the itc values by myself and claimed itc . Now balance is showing in my cgst and sgst . Have I done anything wrong . It yes then how to correct it when my supplier files gstr 3b and I get double input tax credit?
