According to the shopify cheat sheet located at https://www.shopify.com/partners/shopify-cheat-sheet
The checkout object can be accessed in the order status page of the checkout. Shopify Plus merchants can also access properties of the checkout object in the checkout.liquid layout file.
So which properties of the checkout object are available in the checkout.liquid file and when, I either I skipped over the section where that is explained or it wasn't.
Could someone enlighten me as to which properties of the checkout object are available? I've read some hacks about making an ajax call to the checkout api to get back the information, but that seems pretty silly given that we are already in the checkout.

This is an accepted solution.
You can have a look here: https://shopify.dev/docs/themes/files/checkout-liquid
There's an object that will help you identify each step of the checkout process, and derive from that the properties you can query for each one.
