I had not heard it before (or if I did I did not interpret it correctly, eg if one told me "see you in a minute" I would interpret it as "see you in a bit". But there is this podcast discussing it in 2021, and it comes from black community slang from 70s (which is where most slang I encounter comes from). And these terms take a while to catch up usually, but it seems it was already circulating more broadly since 2000s. https://waywordradio.org/its-been-a-minute/ https://waywordradio.org/its-been-a-minute/
