Can't download 1099 forms from TDAmeritrade

TurboTax user for years. Never had this problem before.
My 1099 is available as a PDF on the TDAmeritrade website.
When I try to download it, I get the following message: "Response from TD Ameritrade.   1099 forms not yet available for tax year."
But that is not correct. I spoke with TDAmeritrade and they say this is a TurboTax problem.
How do I solve this?
