Ohhhh.... that makes much more sense to me now. I just had my friend check what his looked like for 2018 and he did get switched to Form 1040. I hadn't heard about that change.
So Marketplace based my payment off last year's earnings, I'm guessing. And I ended up earning more in 2018 than in 2017. So this form makes me pay it back. Got it. I was confused. Now I understand. Thank you!
