Having had to proof government forms for publication far too many times over 33 years for a source of some of the most personal and confidential information people ever divulge, the most probable answer is that someone did not catch a boo boo when proof reading the thing during its galley proof phase, and new forms have not been ordered yet or the goof is still uncaught because you did not call it to their attention. Simple goof, they used a list that started asking if YOU had those issues, and left that one line in the Blood Relative has had it column or heading.
Not a big deal compared to when a tax form has you put your total income on a line that should be for the calculated tax amount that a machine scanner will read as what you owe and send you a bill that will give you heart failure on the spot.
I would not be offended, I would just cross it off and not answer it or give a TS answer!! (Too Snoopy! -- you think I have a dirty mind!!) There are bigger things to make my life miserable, like the tax form.
