You have several routes, in order of immediacy:
Join a live group call or office hours. These run near-daily. You can share your screen and be told exactly where to click and what to enter — a done-with-you walkthrough of whatever registration or step has you stuck.
Ask the community. Mentors are active in it daily, and your question has usually been answered before in the resources or recordings.
Open a support ticket or chat. Included at no cost.
Delegate the task. For sensitive or time-critical items, your account success manager can simply complete the task for you as a paid done-for-you service — recommended for filings where a mistake is expensive to unwind.
For private or confidential matters, one-on-one mentor sessions are available for a small booking fee. Group calls and community help are free and unlimited, so the guidance is to bring anything non-confidential there first.
