Which college do I have the best chance at?

I’m no expert, but Macalester. I believe it is the least competitive to get into. Still a reach. You can calculate each schools ED acceptance rate if you look near the end of section C of the Common Data Set. Every school publishes this on their websites. Have you considered a SAT retake? And I do hope you have some other schools to apply to if ED doesn’t work in your favor-- good luck though.

Also, I have seen that some schools-- not sure which ones-- weight SAT/ACT higher for homeschooled students. If you have good AP scores (4-5) be sure and submit them too.
