The First Officer briefed the ZZZZZ SID Runway XXL; which has the same initial altitude then a turn to ZZZZZ1; as is listed for Runway XY. As we performed the Before Push Checklist we became distracted during the runway response by the confirmation of receiving Report X.  As we began the climb; we then noticed that the FMC was setup for XXL.  As we passed 5;XXX feet; the FMC sequenced to turn direct ZZZZZ1; which was the same flight path for a Runway XY departure for the ZZZZZ SID; therefore no flight path deviation occurred.
During loading of the FMC route the runway was initially loaded as XXL; after verifying with the Ramp that Runway XY was the intended departure runway for the ZZZZZ SID; I began to update the FMC.  At that time the FA informed me of an issue that required the Ops Agent; therefore; distracting me from completing the runway change.  When I returned; in my mind I had completed the runway change.  I briefed the departure and we did not catch the error as the altitude of the turn coded in the FMC; and all the waypoints are identical for the two runways.  As we performed the Before Push Checklist we were also distracted during the runway response by the confirmation of receiving Report X.  We taxied out single engine and my focus was on starting the #2 engine.  As we approached the end of Taxiway G we were cleared for takeoff.  As we began the initial climb; I noticed that the FMC was setup for XXL.  As we passed 5;XXX feet; the FMC sequenced to turn direct ZZZZZ1; which was actually the intended flight path for a Runway XY departure for the ZZZZZ SID; therefore no lateral fight path deviation occurred.  Some additional external factors involved that led to additional distractions are the possibilities of furloughs related to COVID-19.
Air Carrier flight crew reported loading the incorrect departure runway in the FMS but no track deviation occurred due to the flight path being the same. The First Officer reported distraction and COVID-19 job related concerns contributed to the event.
