As the Title says I don’t know how to place the timer on screen (I’m on xbox) and that stat board that tells you how long you’ve been on a certain section, please help me

You're probably thinking of a program called LiveSplit, which runs on a computer. To add this to the video you get from an Xbox, you'd need a capture card to route your Xbox video and audio to your computer, where you can use other programs like OBS Studio to place both the video/audio stream and LiveSplit into the same video/audio file. Capture cards can get expensive. However, unless the rules for your game specifically request this, this is not necessary. Splits are only really used by the runner and moderator, but are not needed to speedrun a game.
