After you file

"Are you referring to some kind of US Postal Service tracking?"
Thing is that I'm trying to return my taxes from foreign country. According to my country national Postal Service tracking my mail has been delivered.

Does TurboTax say "Ready to mail?"
Yes, that's exactly what TurboTax says.

I'm concerned about my IRS return status, because it says "You may not have entered your information correctly. Please verify your personal tax data and try again". That looks pretty weird, because I successfully completed my part on TurboTax.

So should I wait some more time or I need to do something?
