Should I add Sea Foam High mileage with new oil, right after I change it? Or a few hundred miles before the oil change? 2013 Tundra with 189,000 miles.

Good question, Galo. High Mileage in oil works to reliquefy residues and deposits. We recommend adding High Mileage to oil around 100-300 miles before an oil change so the High Mileage has time to clean, and the crud can be drained away with the old oil.
Keep adding High Mileage before each oil change, and it will do a great job cleaning up the crankcase and oil passageways over time!
That said, you can safely add High Mileage to the oil at any time. Just keep an eye on oil color and change it if it gets dirty enough (you might have to change it before your next scheduled oil change).
Hope that helps!
