"an HSA is considered a type of retirement account"
No, it is a "Health Savings Account", not a retirement account. Indeed, the Supreme Court of Ohio specifically ruled that the HSA was not a retirement account, so was not subject to being divided between spouses who were divorcing.
It has similarities to an IRA, but it is not one.
As for your original question, the K-1s don't need to be reported because you don't report earnings in an HSA (yes, like a retirement account), even when you distribute them.
There is not a way in TurboTax to report a K-1 distribution into an HSA, even if you wanted to do it.
So I would just ignore the entries on the K-1s and declare victory since it really doesn't matter to you what their paperwork says.
