Did you mail your return?
"My mail status shows that my mail has been delivered."
Are you referring to some kind of US Postal Service tracking?
"TurboTax return status hasn't been changed."
Does TurboTax say "Ready to mail?" TurboTax will not know if you actually mailed your return or not. So even if you mailed it, and the IRS has received your return, TurboTax will still say "Ready to mail."
