Are you using TurboTax Online or the CD/Download TurboTax software?
The CD/Download TurboTax software does not have a special section for sales of cryptocurrency. You enter it the same as if it were stock.
In TurboTax Online I believe the full title of the section is "Stocks, Cryptocurrency, Mutual Funds, Bonds, Other (1099-B)."
See the following FAQ.
How do I report Bitcoin or other cryptocurrency as a capital gain?
