Sidebar disappeared only on home page – Genesis 2.1.2

Novice here – I didn’t build my website but do make changes a lot (text, not coding). I have no idea what I have done, but suddenly my primary sidebar appears on every page but the home page. I am using Genesis 2.1.2. I have an important event coming up and really need this on my homepage. Thank you in advance for your assistance. I really appreciate it. https://www.lifelineatl.com.
