TurboTax realized that he did not have HDHP coverage in 2024. However, when you answered "Self" to the question of "What type of High Deductible Health Plan did [name] have on December 1, 2023?", then TurboTax thought that he had HDHP coverage in 2023 but not in 2024, so the coverage seemed to have lapsed.
In point of fact, since the IRS considers that taxpayers who have conflicting coverage (like Medicare) do not have HDHP coverage (even when they do), then you should have answered NONE to that December 1, 2023 question.
This would prevent the lapse message.
