Narrative:

I inadvertently flashed a handoff to sector 30 instead of sector 31. The error was not caught until the aircraft crossed the boundary. I effected a manual handoff to sector 31. I was not aware that a system deviation was turned in until 9 days later. I believe this deviation occurred by typing the wrong sector number into the computer and not catching it because of alternating gndspd and sector number in the bottom of the data block.
