Enter the sale using the "Stocks, Bonds, Mutual Funds, Other" interview telling TurboTax (I assume) that a 1099-B was received. Fill out the information called for in the default "Security sale" TurboTax input form that comes up. When asked when the stock was acquired type in the word "inherited". TurboTax will place this trade on Form 8949 as a sales category E trade, i.e., long term.
