How can I edit my information near the Contact form on my Details pages?

That information is provided by our Agent Information Add-on for Single-Agent accounts. To change it you just login at https://idxaddons.com with your IDX Broker API Key and go to Apps then Agent Information.

If you have a Multiple-Agent/Office account, you can change the agent’s information at https://middleware.idxbroker.com/mgmt/agents and your Office information at https://middleware.idxbroker.com/mgmt/account.
