Thank you sooo much for your answer! I seriously freaked out already. You really saved me, I will definitely follow your suggestion.Don't worry, its not a desperate situation at all . Just reprint the same Credit Card form that you filled originally , fill it with updated data and send it by email identity@fbi.gov or fax (304) 625-979 to them. I sent mine by email . Mention the day your application was sent to them. After that, you can call or email them to confirm that they received it. They will confirm that they have received it and sent it to the appropriate department.
