Does asking for TA or RA position hurt admissions in a fully funded program (physics)?

[Physicist]

I am filling out applications for PhD programs in physics and not sure how to respond when a school asks if I would like to be considered for a TA or Research assistanship. The answer is yes I would love to teach / do research, but no, I don't need the money to supplement whatever stipend they would be providing (my parents can help me) . I want to answer in the way that makes me the most competitive for admissions. Hope that makes sense! Does anyone know?

This question does not affect your competitiveness for admissions. Answer yes in your case.
