No professional reviews your scan or any generated materials. You decide how to proceed and should consult a qualified professional for advice about your facts.

If you want an attorney to review your situation, Law Office of Alexander Powell, PLLC is a separate law firm owned by our founder, Alexander Powell. It handles tax controversy matters in the District of Columbia and Maryland. It is a different company from Cited Authorities LLC, and choosing to contact it is entirely up to you.
Contacting the firm does not make you a client. The firm becomes your attorney only if it accepts your matter after a conflict check and you both sign an engagement agreement. Until then, do not treat anything you send as protected by attorney-client privilege, and do not rely on any deadline running or being handled on your behalf.
