In my case TurboTax Premier online it didn't work for me because I have more than 2000k transaction and this software does not support these larges files, and TurboTax Desktop does not give you instructions on how to upload the CSV file but, just ask you if you had it any Crypto buy and sell during the year, but it does not give you the option to upload the files to correctly file my taxes, this is very frustrate when you paid for something that it does not help me to file my taxes correctly.
