Hi @incontrolcc - like Glyn said you can add canonical tags to pages in Squarespace using the page header code injection feature.
However if I'm following you correctly, you might want to be cautious — it sounds like just one section of your homepage contains this information about packages which is then replicated on a separate Packages page. You wouldn't necessarily get penalized for duplicate content here, since I'm assuming the homepage also includes other sections of content that are distinct from the Packages page? It's not unusual for a website's homepage to "preview" info that is explained in more detail on other pages of the site. Generally you would use a canonical tag to explicitly declare which version of two identical (or close to identical) pages is the preferred/authoritative version.
If you canonicalize your homepage to your Packages page, this may result in less search visibility for your homepage, which probably isn't the intended result!
