What version of Thunderbird?
Have you tried opening the Contact Sidebar (press F9) in the composition window and selecting the preferred address from that list?

Version 78.6.1 is an email that is not in my contact list. So I am typing that address in the address section of an email, but autocomplete is putting in, which is in the contact list.

In other words, autocomplete is entering an email from my contact list for an address that I'm trying to enter manually (because it is not in my contact list).

Just ignore the autocomplete entry and continue typing. The text should turn red once it no longer matches anything in the address books. At that point it should automatically remove the remainder of the auto-complete address.

You could also add to one of your other address books such as the history address book. No need to full out other contact details if you just want to be able to choose it from the auto-complete popup window.

You right click in the address and edit it.

Either that or type "xyz@". That is, assuming that the address "" is part of your previous contacts.

Depending on how your preferences are set, it will prefill addresses from all the contacts you have PLUS all addresses collected in the "Collected Addresses" address book. You can change your preferences under Tools –> Options –> Composition –> Addressing.

Likewise, if you use the Cardbook extension, there is a preference telling it what address book(s) to use for autocompletion.

If you have no idea where the "" comes from, often, the culprit is found in the "collected addresses" address book. Search for that address and delete it from there.
