I assume you mean a RMD (required minimum distribution). You will receive a 1099-R from the institution where your retirement account is held detailing the transaction. Enter the information on the 1099-R when you file your taxes next year. You can use any version of the downloaded software to enter this information, assuming Turbotax doesn't change the software capabilities next year.
You do not pay tax on gains and losses within a retirement account, but pay taxes on the amount withdrawn.
