If sold shares of stock this year, and did not have tax taken out. what do i do?

You upgrade to the Premier edition to be able to report the sale of stock.

If you come up "underpaid" because of massive taxable gains - which I'd guess is unlikely - the if it happens that the gains were all late in the year you annualize your income - TurboTax will help you here- to show that the extra income came late in the, minimizing the underpayment penalty.
