@WindyCityME Not an accountant and I'm not giving tax advice. My guess is that when you file your TY2020 tax return in April 2021, that they will "take back" the $1,200 stimulus payment if in fact you were over the income threshold to qualify. I'm sure you're not the only one in this situation. I don't see a way for them to modify anything about the 2019 1040 that gets filed July 15, 2020, so your idea of delaying your 2019 filing until July might work, at least temporarily.
Regarding the "Payment Status Not Available" message - make sure you enter the information in the form exactly as it was on your last tax filing, including capitalization(s), punctuation if any, etc. IOW, their system needs an exact match, not a "close" match.
