Secondary update: I refilled out the form via a link Support sent me, however my tax documents section of Settings still lists my old tax interview from September (though it now says validation failed) and has an option to retake the tax interview a third time. I've tried emailing Support on if I should retake the tax interview again to no response. I might just retake it again if I don't get any response since it says to on my settings page? This has been beyond frustrating and it starting to get ridiculous.
