I do not understand. What do you mean that TurboTax tells you that you are mistaken? What do you mean that TurboTax tries to fill it out a 1099-SA? What is TurboTax actually telling you?
There is nothing wrong with one HSA bank acquiring another mid-year. As for the two 5498-SA forms. that's of no matter, because you don't enter anything from the 5498-SA anyway.
But please put some context around what you are saying. What is TurboTax saying exactly?
