Once you submit your return in TurboTax Online, you'll see its status on the Tax Home screen of your account. We'll also send you emails letting you know when your e-file status changes.

You can use the IRS tool Where's My Refund to check if your e-filed return has been received.

If you don't see an e-file status for your return in TurboTax Online, you may have filed your return in a different account or using a different method.

If you used TurboTax Desktop:

1. Select File.
2. Select Check E-file status.
