A 20 fl oz bottle of soda holds 2 1/2 cups, about 591 mL. For measuring, the 2 cup line plus a 1/2 cup does it, or pour into a 4 cup liquid measure and read the 2 1/2 cup mark.
Twenty ounces is also 1 1/4 pints. That is close to a British pint, which is 20 imperial fl oz; converted to US units it is about 19.2 fl oz, so slightly under this bottle.
Some recipes for brines or punches list ounces on purpose, because cooks pour straight from bottles. Read those as fluid ounces. If the ingredient is a solid sold by the ounce, the label is weight and a cup measure is the wrong tool. See the ounces to cups chart.
