Looking for more current information on submitting a forum 1 as an individual for an SBR. I have already had my lower receiver engraved and now need to submit the paperwork. I am planning to do eFile. I know I need fingerprint cards x 2 and passport sized photo x 2. What else do I need?

When efiling, do I submit the form online and then mail in the forum with fingerprint cards and photos? Also is the CLEO sign off even a thing any longer or do I just need to but the CLEO name, dept and address on the form.
