I figured it out, but it still doesn't make any sense. I was using the auto fill that I had saved, so I figured that must be the right login. Turns out they have a bunch of login names tied to my email? So I figured I would try to make a new one, since apparently it's let me make a bunch of new ones in the past, and went through the create account process and and told me I couldn't because I already have an account tied to that SSN, and gave me THAT username (one I hadn't tried before). So I reset the password for that one and logged in fine.

Weird thing is it let me reset the passwords for two other user names. Makes no sense
