It seems that there is a system issue with Form 1040 - Schedule 1 that is rejected by the IRS. 

The rejection code is : S1-F1040-080-03 - Schedule 1 (Form 1040).

To Turbotax: Could you please provide an explanation and when this issue will be resolved?

    I have the same problem, but I can't resubmit my return because TurboTax apparently didn't save anything I inputted. Do I have to completely redo my tax return?

    • More than likely. It's odd that it wouldn't save your info. Did you use the software or online version.

    I finally found the file. But I had to open it from the file location because Turbotax wouldn't open it when I clicked on continue tax return.
