If you filed with TurboTax, and stimulus did not show in your account, is it coming by mail?

You have to start by checking the IRS web site.

If you received an e-mail from Turbotax about the IRS mistake with the refund transfer accounts, then the deposit should be made Friday or today by SBTPG, but direct deposits can take up to 2 extra business days to appear in your account, depending on your bank's policies on deposits.  If you didn't get the email, you aren't in that group of customers.

You might be getting a late deposit, a check in the mail or it might say "no information" in which case the IRS is not making a payment to you and you will claim the credit on your tax return.  There might be many reasons why the IRS can't or won't issue a payment; Turbotax only has information about one specific situation.
