Trying to migrate from WordPress.com

I have a WordPress.com site, but realized I needed the capabilities that a hosted WP offers. I’m trying to switch my .com site to my .org site, which i’m fully registered at and WP has been downloaded to the Bluehost platform, but running into several issues:

1) Current domain is registered at WordPress.com
2) I cannot access my .com dashboard to export the data (which there is only a title copy and a free theme selected, and I’d delete it but it says I can’t cause my domain is registered there).

How do I get rid of my .com site so my site is fully on the .org one so I can begin building it? Any info would be great!
