Thanks for your question.
Complete the application as accurately as you can. If you started an internship, but are not yet finished, list that as an internship experience "in progress." If you do not have any experience yet, indicate that you do not have any professional internship experience on your application.
Depending upon the specifics of the application, you may have experience, but not through an official internship. If that is the case, and you believe it would be beneficial to include on your application for this position, please include it. Employers tend to look for the relevancy and impact of your experiences, whether an internship or not.
I hope this is helpful. All the best.
