You may need to View/Print your return and check the Recovery Rebate Credit Worksheet.

When you go to the Federal Review and enter the stimulus amount you received, TurboTax will calculate what you should have received and the balance due is a Tax Credit for you.

It is also telling me that I received the correct amount. I even restarted the taxes to see if it was an error on my part. I am thinking it is turbo software. Short of printing and filing by mail to ensure that the credit is received. Idk what else to do.
