As a Georgia resident, how do I report a corrected 1099-B from broker after I have already filed the return?

Prepare an amended return - make the changes.   If the changes make a difference in the amount of your refund or amount due, file the amendment.   How do I amend my return?  

thanks for your response. After checking the corrected 1099-B, it appears there is no significant difference in the amount so I think I am clear. Thanks for your time.
