The front page has 8 widget areas - Front Page 1, Search Bar, Front Page 2 Left, Front Page 2 Right, Front Page 3, Front Page 4, Front Page 5, and Front Page 6.
These have all been set up for you, if you used the One-Click Theme Setup.
You can edit each widget area from Appearance > Customize > Widgets, or also Appearance > Widgets.
If you don't want to use a particular widget area, don't add any widgets, and it won't show on your front page.
Of course, all widget areas can be customized with your choice of widgets, although some styles may need adjusting.
