When you prepare your tax return for 2020 in TurboTax, you will be prompted to enter how much you received for your stimulus and then the program will calculate the amount of stimulus due you based on your income, number of dependents and payments already received. If any additional stimulus is due you, it will be used to reduce your 2020 income tax liability, and the balance will be refunded to you.

You will see the options when you are done entering your tax information and proceed to the review process.

You can file a tax return in 2020 to get your stimulus check, even if you aren't required to otherwise.

Do you mean your Refund? Did you efile or mail your return? When? They didn't start opening the mail until June that was stacking up. Back in March the IRS closed their processing centers and stopped processing mailed tax returns.

If you efiled....Was your return Accepted?When you efile you get back 2 emails. The first email only confirms the transmission. The second email says if the IRS (or state) Accepted or Rejected your efile.

Then only the IRS can tell you. IRS Where's my refund https://www.irs.gov/refunds/
Make sure you are using the refund amount from your actual federal tax return and not the combined amount Turbo Tax showed you at the end. That was for federal and state combined.

When you log into your account you should also see the status and if it was Accepted or Rejected, Started, Printed, Ready to Mail, etc.  what does it say?

Thanks, but I’m. In not talking about my stimulus check, I didn’t receive that I did not receive it either, I mean $ 1690 that I should have received and supposedly my check was already sent and I never received it, I want to know where it is because the money never reached me.
