My understanding is that the sin of abortion is reserved to the local Bishop, if a priest hears it in confession he will ask the woman to return after he has gotten leave from the bishop to absolve. The procedure varies by diocese.

I don’t know the process, but the person involved with the abortion is excommunicated at the time of the killing; no Church authority needs to make it happen.
