I've been randomly searching forms and I pulled up this https://www.sec.gov/forms. However, I'm financially illiterate to the point that I don't know what terminology I'm looking for.
I've seen that FED buy backs tend to happen in the form of issued warrants or bonds, which kind of looks like 424B2 and FW1 Forms, but I haven't been able to identify if the fed's are the ones buying these bonds as a means to "bail them out".
I'm also at a complete loss as to figure out how much a company is buying it's own shares up. SG 13G and 13 F seemed promising, but I haven't been able to match a google search with of company buy back with the actual sec form that provided that information.
