Where does this nutrition data come from?

From published food composition data, most of it traceable to USDA FoodData Central. That is a database of analysed and calculated values for generic foods, which makes it the right starting point for formulation and for a first estimate of a recipe.

Can I use these values on a label?

Yes, with care. FDA accepts values computed from a recognised nutrient database rather than requiring laboratory analysis. The responsibility for accuracy stays with you, so the database entry has to genuinely match your ingredient: the right cut, the right form, the right moisture state, and the right supplier where it matters.

When should I pay for laboratory analysis instead?

When raw material varies significantly batch to batch, when your process changes composition in ways a database cannot model, when a nutrient sits close to a claim threshold or a rounding boundary, or when a customer or regulator asks for analytical evidence. Anywhere a small error would change what the label says, testing is the cheaper option.

Why do two sources disagree about the same food?

Because they are describing different samples. Variety, season, soil, feed, ripeness, cut and preparation all move nutrient values, and databases report a mean from a finite sample. A spread of ten to twenty percent between sources for a fresh product is normal rather than an error in either.
