Welcome to the Q&A Forum

Yeah, unfortunately, that's core Knowledge Graph (not a Featured Snippet), so it's coming from a partnered data source. I'm not sure where they're pulling this from, though, as the Wikidata/Wikipedia entries seem correct: https://en.wikipedia.org/wiki/Free_Shipping_Day There's not even a "report" option on this one, so I'm afraid Alick300 is right - you're going to have to contact Google directly, I'll ask around on Twitter, but Google isn't transparent at all about these data sources.
