Did Harry time-turn the day Hermione died, and, if so, what did he do?
Yes. When he went into the room with Hermione’s body, he turned the time turner and transfigured her body into a ring while also transfiguring something else (presumably something very small) into a copy of Hermione’s body. He then hid from his past self and left the room just after his past self entered. After the transfiguration wore off, the ‘body’ dissapeared.

Yes, but he could do all of that with a single twist.
