I check my bank account today in the US, my $1200 stimulus was direct deposited on April 29th. My details: I did not file a tax return 2018. When I do file for 2018 I should get about another $600 (refund).
My wife and I have filed jointly for the last 8 years, not claiming her as a deduction, but myself head of household. She did not have an SS number, but her income was claimed putting me into a higher tax bracket.
I'm happy with the $1200 and have no gripes about not being $2400. There is a class action lawsuit filed for persons like us. Any further money will be considered as found money.
