switching from wordpress.com to www.ads-software.com question

Hello,
I started a website using wordpress.com (wp.com) and am now trying to switch over to wp.org. I have had the wp.com site for 1 day, so needless to say I don’t have any information or images to transfer, I just want to make sure that when I go to my admin page it is for the .org site.
I am using BH as a hosting site and have just now redirected my domain name to BH instead of wp.com. However, since I apparently don’t have to use MAMP on my mac to install wp, I don’t understand how to download wp.org anymore? How do I access the wp.org dashboard because whenever I go to https://www.perpetualflow.com/wp-admin/ I am routed to the wp.com site.
I hope this is understandable and please let me know what else I can provide to make troubleshooting this easier.
Thank you in advance.
