Narrative:

At cruise; pilot flying (PF) loaded runway and approach he thought he would get. PF got up to use lav. When he came back I sent for a new ATIS so I could check approach. When the ATIS came back I was confused about runways they were using it said 25L which we expected but it also said 19R and 19L. I said did lax add new runways. Then we realized I had sent for las ATIS. Resent for right ATIS. This started us to get behind. We started to get busy with ATC instruction changing speeds and fixes. We were given direct gramm and couldn't find it on our flight plan so we typed it in and went direct. I reload arrival and picked pgs transition and gramm was there and then went direct to that gramm. I still needed to load approach and do approach checklist. We were given descend via and set lowest altitude. We were already past TOD and didn't notice it right away. When we realized we had passed TOD; PF clicked off autopilot to meet crossing restriction our speed got high we put out air brakes to help. I was trying to help so I never load approach. We were at riivr then and there was nothing in the box after that because when the PF had loaded the approach he didn't pick the riivr transition. While I was loading approach that is when we got off course. I finally got approach loaded with the riivr transition ATC noticed we were off course and we told him we were correcting. We got back on course and stable and landed safely. Socal gave us a number to call when we got on the ground. We called when we got on ground and we explained what had happened and they seemed ok with that. They wanted us to know that we were off course.
