It was confusing for me as well. But I figured it out. Although Robinhood does give you a document summarizing your crypto transactions through them, that PDF is not what you submit. In Robinhood you should see you also got a file called "Robinhood Crypto (CSV)". That is what you turn in to TurboTax
In TurboTax, when click "Add investments", you instead go to the bottom and select "Enter a different way". From there, you select "Cryptocurrency" and continue. From there, it asks if you want to log into your exchange (Robinhood, in this case), or if you want to upload the CSV yourself. I already had it downloaded so I chose to upload it, but you can choose to log into Robinhood if you prefer. From there, you select "Robinhood Crypto (CSV)". That should be it.
