TurboTax imports the numbers that Robinhood sends it. But the numbers come from a special import file that Robinhood creates, not from the PDF.
Was there a gap in time (of a day or more) between when you did the import and when you downloaded the PDF? It's possible that Robinhood made some adjustments during the time between the two operations. Delete the imported information, do the import again, and download the PDF on the same day. If they are still different, ask Robinhood why the numbers in the import file that they create for TurboTax are different from the PDF.
