If TurboTax is indicating that you need Form 5329 for something regarding your HSA, it has to be related to contributions HSA, not distributions from the HSA. The penalty for early, nonqualified distributions from an HSA is calculated on Form 8889, not on Form 5329.
Make sure that you have visited the HSA section in TurboTax and have answered the questions TurboTax asks to determine the amount that you are eligible to contribute to an HSA for 2018.
