I manage my father trust and get paid a fee. I know I don't have to pay SE tax b/c my work doesn't raise to business level. How to tell TT I don't have to pay SE taxes?

I manage my father's trust. I receive an annual fee for the work I am doing. I know I don't have to pay self-employment tax because the activity does not raise to business level, I don't do any trading and it is not done at a professional level. In the past my old CPA told me so and I have done so every year since. This year, however, turbotax wants me to pay self-employment tax. How do I tell turbotax I don't have to pay self-employment tax? Thanks Luca
