No need to empty it and start over. Power steering fluid and its additives can last a really long time. If you add with the engine running, and you already see it's expanding and filling the reservoir when you stop the engine, where is more fluid going to go? On the ground. As long as it's not sucking air causing a buzzing noise, drive it until the air works its way out, then when the level is low with the engine off, add some more. That could take days.
