Why was my stimulus rejected?

You may have filed a tax return and the e-file may have been rejected. 

There is no filing for the stimulus checks, so that could not be rejected.

Apparantly if I used Turbotax, they do not know my bank account number.  How do I fix this?

 Check the IRS website and update your bank information if necessary.  AGI is line 7 on your 2018 return and line 8B on your 2019 return.  Refund is line 21a of the 2019 tax return. and line 20a for 2018
