Missing subitem after attempting to move

Hi, I was attempting to move 5 subitems using the Move to Item function from one board to a new board within the same folder. When asked to choose the parent item I typed in the name of the folder followed by the new board name and hit enter. They moved! Problem is I didn’t hit undo and now I cant find them. They did not move too the new board and they aren’t archived or deleted. Can anyone help?
