I didn't put my patronymic name, because it is not a middle name. But during the interview officer added this as a Middle name.
As I found out later, I had to provide my name with patronymic as part of the Other section of a form, to avoid redoing a background check. But I am in US already and processing AOS, not Consular processing.
So if you win, most likely, you would be able to deal with it during form submission.
