I'm in the same position. I'm 22, lived with my significant other all year. I have attended no college, and I made way over the threshold to be a dependent. I had accidentally marked that someone could claim me when I filed. No one claimed me, obviously.
It wouldn't make sense for people who were not claimed but marked the box to NOT get the stimulus check. If the IRS is doing any sort of verification, they could easily see our incomes to show that we couldn't even BE dependents. There is no way we wouldn't get one. For all of us in this boat, I really hope the IRS doesn't fail us.
