How to get started: checkout upsells
This checkout.liquid feature was sunset. Shopify moved to Checkout Extensibility. Checkout.liquid is no longer around. To learn how to do this on the new checkout, go here: https://help.upsellplus.com/en/article/how-to-get-started-checkout-upsells-checkout-extensions-kr97nq/
To create a checkout upsell:
Click 'Create offer' > Choose 'Checkout'

Select the type of checkout you have active

Checkout Extensions are for the latest checkout by Shopify. If you've never customized your checkout before or just moved to Shopify Plus, it's likely you're using this new checkout. If you have customized your checkout before, it's likely that you're using checkout.liquid.
if you only see one option, it means your store only has access to that type of checkout.
