If this wasn't helpful, what information can I provide that will be? Did you file by efile or mailing?
I filed with Turbo Tax the extension and i have not heard anything else about it. How do i know if it was sent to the IRS?
You will receive a verification email.
It is normally between 24-48 hours, but it may take longer this week.
Don't worry, because you filed on April 15, 2019, your extension is considered timely filed.
