TurboTax does not import your 1099 data from the PDF. Robinhood has to create a special import file for TurboTax to use. Contrary to what the Robinhood rep told you, if the data is not available it's because Robinhood has not yet created the file that TurboTax needs, or has not yet made the file available to TurboTax. I suggest that you try again in a week or so.
