Dear Iamcste,
Based on what you provided, you seem to have the foundation of a competitive profile for most top 20 programs. Without knowing your GMAT, it is hard to comment beyond that, but you appear to have a good GPA and a successful track record in your career. In terms of extracurriculars, it is important to show you have a life outside of work and where possible that you have taken on leadership roles as well. If you don't have many extracurriculars or leadership in any, that will no way result in a negative admissions decision. Schools merely look to see that you are a well-rounded person and gain insight into more of who you are as a person.
What makes the difference for any applicant is how well you put your application together. It is imperative you present a strong rationale for why you want a MBA, how it fits into your overall career plan, and why the school you are applying to is a good match for you. Likewise, you must distinguish yourself from the competition and demonstrate successful leadership experiences/evidence of leadership potential. Your school list seems a little long, so I would encourage you to visit/do further research to come up with the 5-6 schools that best match what you want in terms of curriculum, culture and resources (including 1-2 safety options).
Best of luck,
Lisa
