I'm running version 1.21, but I think this may apply to other versions as well.
Take a look at the bottom right-hand side of the screen. You should see something that says Spaces or Tab-Size.
Mine shows spaces, →
- Click on the Spaces (or Tab-Size)
- Choose Indent Using Spaces or Indent using Tabs
- Select the amount of spaces or tabs you like.
This only works per document, not project-wide. If you want to apply it project-wide, you need to also add "editor.detectIndentation": false to your user settings.
