how do i uninstall ios 14 beta?

See here: How to uninstall iOS beta software - Apple Support

I have no idea what those directions were. I have tried to remove it by restoring my phone but still having issues. My banking app will not let me open it, says I have a jailbroke phone? I am not tech savvy.

Use the information provided to you by Apple when you signed up to be a developer.

If you aren't tech savvy, why did you install a developer beta?

Directions on how to uninstall the beta are on the beta website.

You really do not have to be so ugly about it. This should be a friendly forum. But thank you for your unsolicited opinion.

It is also rude to theadjack, if the OP wants to complain they can. But thank you for your unsolicited opinion.
