The signal was found in the archived data in October, but it was actually received on April 29, 2019: https://www.nytimes.com/2020/12/31/scien...trial.html
Interesting idea if something from us would have caught their attention that amount of time before. If they have a Square Kilometer Array equivalent, however, they would have been able to detect our everyday radio leakage for many years, and thus know a technological civilization is here.
If (which is of course a huge if) this were an alien signal, I'd suspect it's one they re-send occasionally to get our attention. I'm sure Breakthrough Listen is scouring every dataset they can find to see if there is a repeat of this somewhere so it can be studied further. Note though that human RFI may also repeat for whatever reason.
