Same thing here. The customer service is stuck on cleaning the cache when turbo tax acknowledged in the link below (not a surprise but I am unable to access the link now) that the issue was on their side and they were working to resolve it. Customer service won't even transfer to tech support now as they can probably give us better info. One rep told me that they are the tech support now due to the call volume.

I will have to try this as well but I found a reddit post about some folks tweeting the CEO directly about this issue and hearing back from his office.
