Sales of crypto currencies are reported using the "Stocks, Mutual Funds, Bonds, Other" interview, telling TurboTax that no 1099-B was received. As to the "type" of investment sold you can simply use "Everything else."
Even a "swap" of one crypto currency into another crypto currency is considered a reportable sale. You convert the new crypto currency received into US Dollars at the spot price of the new coin at the time of the sale; that's the reported "proceeds" for the sale of the old coin and it's also the basis of the new coin.
