I filed my taxes a while ago, however I found out after I was claimed as a dependent, and my return is rejected. How can I fix this? Is it something I must do in person?

I filed my taxes a month ago, however I found out afterwards I was claimed as a dependant. I have attempted to fix my return, however it got rejected again. Is this something I must do in person? Is there a way for me to refile, and fix that one part?
