I think there are only 16 straights possible since you can't start with 17, 18, 19, or 20

Yes, you're right. In this case, the Powerball comes last. So increasing straights can't end with 1, 2, 3, 4, or 5. However, you could have wrap around straights. So 15 or 20 depending if you allow the wraparound.
To give you a more charitable interpretation, the South African lottery Powerball can be 1-20 so there are 20 straights possible so 20 in 42,375,200. Or roughly 1 in 2,000,000 or roughly 40,000 years of weekly draws to see a straight.
