Checkpoint system+ Main menu help?

Hi. I’m working on a paper 2d project, and I made a checkpoint system and a main menu for it. When you press “Start New Game”, you go to the first level. But when you saved your game in level one, quit, open the game again and then press start new game again, It will send you to that savepoint. how do I make sure when the player starts a new game, it will automatically send him to the start of the first level? Thanks
