Narrative: While I did perform a visual inspection of the flight deck in accordance with FOM requirements on all flights departing the US to Country X; I never received or completed a search form. I realized this about halfway to our destination. I called the flight attendants and asked them if they'd performed a visual inspection during their pre-flight; to which they responded in the affirmative. I also called ground handlers in ZZZ when I got to ZZZZ. The gentleman confirmed with me something along the lines of; 'the cleaners perform the search of the cabin while they're cleaning and disinfecting the aircraft.'This was a 'turn around' with maintenance items that needed addressing and [aircraft] disinfection that needed accomplishing; so some task saturation. Furthermore; my normal routine is typically to trade the Gate Agent's paperwork with my completed security sheet. With the auto passenger count closeout; that moment is no longer consistently there. I think we could benefit a lot from some more standardization (pilots; flight attendants; and Customer Service) regarding the completion of the security sheet. With the new below wing ground handling and the new procedures in ZZZ; there are changes in the way aircraft are turned and the people I interact with. I will most likely remind myself and my crew about the security sheet during my Pre-flight Briefing when I mention passports. This way; verifying the paperwork is received and goes out the door can be a collaborative effort.


Second narrative: When airborne on our flight to ZZZZ the Captain realized that he didn't receive; fill out; and return the paperwork saying that he did the security sweep of the aircraft. He did perform the sweep when we first arrived at the aircraft and asked the Flight Attendants to see if they did their sweep as well. They also performed the sweep. When we landed in ZZZZ my Captain called the ground handlers and explained the situation and confirmed that he did the sweep.Our plane arrived late into ZZZ. We had to do a quick turn and wait for cleaning to [sanitize] the aircraft before our crew and passengers could get on the plane. Maintenance had to be performed on the aircraft. A lot had to be done in a short time.On the quick turns everyone needs to slow down and make sure they are doing things correctly even if it means we won't get out on time. If the Gate Agent; Flight Attendants or Pilots took time to remember the security sheet then it would have been filled out and given back to be filed.


Synopsis: Air Carrier flight crew reported failing to complete the security sheet due to pre-flight work overload that now includes the added task of ensuring the aircraft was sanitized.
