I believe what you mean is there were three transfers and they were all taxable, but one of them is not showing as taxable on your tax return. Often, this would be because there was a code "G" in box 7 of the Form 1099-R indicating the money was rolled over from a taxed deferred retirement account to another similar account. I assume it is the HSA distribution that is causeing the trouble. Can you clarify was is in box 7 on that form?
