Because you separated from service from the employer providing the original 401(k) plan in or after the year you reached age 55, ALL distributions you make from the original plan in or after the year in which separation occurred qualify for the age 55 exception. As Hal_Al indicated, a distribution in 2016 (or any other distribution you may make from the original 401(k) plan in the future) qualifies for this exception.
The the administrator of the original 401(k) plan should know your age and your separation date, so the administrator should code the distribution with code 2 in box 7 of the Form 1099-R reporting any distributions from the plan. Code 2 indicates that an exception known by the administrator (the age 55 exception) applies. In such case, no Form 5329 will be generated by TurboTax with regard to this distribution. If the administrator uses code 1 instead, it will be your responsibility to claim the age 55 exception on Form 5329.
