Get your taxes done using TurboTax

Well...one thing to try.

If you go back to your account, and re-download a new PDF copy of your tax file...it should contain an" Electronic Postmark" sheet

....That sheet should show the a)  Submitted date and time, and then b)   a separate line for the date of acceptance by the IRS.

 

That's about all you can do to confirm it's done.
