I have heard of a few people like that. I actually lucked out the other way. If they had used my 2018, I wouldn't have qualified, but by 2019, which I had already filed, I do. (2019 was not as strong as 2018).
This seems crazy to me that someone would or wouldn't qualify depending on if they just had happened to file 2019 early or not. Also doesn't seem right that someone who happened to have a big payday due to circumstances like yours, selling a business should be penalized. Probably a result of this thing being rushed through without thinking everything out. You know the original plan was Mitt Romney's $1000 for every American. Maybe they should have just kept things simple. Like Blackjack counts, keeping it simple is sometimes best.
