I believe stimulus money was / will be paid regardless of whether you filed taxes?
I don’t know. Last time the stimulus money was paid out it was based on your last tax filing and many folks, like my son living here in England, had not filed when the money was paid out so they used his return from the year before.
It will soon be past the October 15 extension filing date so might well be worth filing a 2019 return even if no taxes due.
