Everything was working fine with Thunderbird and all of a sudden I get an error message when trying to get mail that says: Sending of username did not succeed. Mail server responded auth-status: Invalid login or password. Nothing has changed with my account and I can login using webmail. I have verified all the settings for my ISP (Centurytel) and they are correct.

Well, tried all of that and still no luck. Contacted Centurytel again and everything on their end works. I can log in to webmail. They confirmed by settings on Thunderbird are correct but it's not letting me log in.

Can you post what the settings confirmed by Centurytel are?
