The SSA 3373 BK, and SSA 3380 BK forms are sent by the state agency not your local office, so they are not found at the SSA site.
You should use the form with the latest date.

I do not think you understand SSA definition of disability. You medical symptoms have to be severe and meet or equal a listing from the impairment. You have to be sick enough not to do sedentary work (eg) playing a piano is a sit down activity.

You only "volunteer" job should be making sure SSA gets your medical records.
