iOS 14 beta

hi I installed the iOS 14 beta on an iPhone 6s Plus since it was giving me problems I then booted my phone so I erased everything started from afresh thinking that it would have deleted the profile for me and I would able to use the normal iOS update that was given by Apple. So that didn’t work and the I watched videos on how to remove the iOS beta 14 show the website showed me the steps which was go to general and then click on profiles so I did that and I realized that my iPhone did not have an option to go to profiles so then I searched up what could be the problem and it mentioned something about if you can’t find the profiles section that means you don’t have any profiles installed. I don’t know what to do if you could please help me that would mean so much.
