Will I see activity of forms submitted by sub accounts?

Hello @rmorris19 - I feel there's a misconception on how you think sub-accounts work. They normally don't submit forms, your users/clients/visitors are the ones submitting it in common use case scenarios.

However, if your current workflow is indeed revolving around your sub-accounts acting as the form respondents, then you can check and see their submissions from your Submissions Page like any normal submitter.
