Just in case anyone else is in the same position and missed the fine print of the stimulus payments, I'm posting what I found out from a representative of the IRS.
If anyone claims you as a dependent on their tax return, even for a brief period, and you are over the age of 16, there will not be a payment on your behalf to neither you nor the person claiming you.
I asked her if stay-at-home parents essentially don't exist in the land of COVID relief. She laughed and politely affirmed this.
So, there you have it. If you want to receive payments, don't let others claim you. That is all.
Good luck to you all and stay well!
