TurboTax Desktop currently does not support the importing of cryptocurrency .CSV files. However, @harbinger910 did find a workaround using a .TXF file if your platform supports it.
Another workaround you can try is to start a TurboTax online account, import your cryptocurrency data and then save the .tax file to import into your desktop version. To do this:
- While you are in your tax return, click Tax Tools on the left menu.
- Click on Tools.
- In the pop-up menu, click on Save your 2021 return to your computer.
