Why do I keep seeing "undefined" any time I click on anything? I already paid and was waiting for state, went back to look at something, and now that's all I can see.

I just got a 1099 G/INT form in the mail and came back to TurboTax since it said I couldn't submit until at least 1/21.  I wanted to add it, but couldn't find the place to do so.  Now, any time I try to access anything, either by app or computer, it just loads a page that says, "undefined."  What do I do?  I already paid... is something wrong?
