The TV series BMF (Black Mafia Family) came back on January 6, with Season 2 premiering on that date at midnight on the Starz app, followed by its linear debut at 8 p.m. ET/PT in the U.S. and Canada.
If the question refers to a specific "20" date in another context, additional clarification is needed. But based on the information, the notable comeback date for BMF's second season was January 6.
