My return was rejected by the IRS. The error code is F1040-478. I do not see that code on the error list provided by Turbo Tax. How do I correct it?

I followed the steps in Turbo Tax to try to fix the error. I efiled a second time and my return was rejected again with the same error code. What is needed to correct this error? F1040-478

This is what that reject means: This return cannot be filed at this time due to a processing error that will be corrected on March 13, 2026. On or after this date, open the rejected return, review it for errors, and resubmit the return for electronic filing.

Thanks Catina, I had the same rejection message this morning.  Do we need to make any changes, or just click "errors corrected" and resubmit?

Actually I have one other question - I had to pay to submit my state, which also got rejected due to the federal rejection.  I'm not going to have to pay to refile, am I?

The latest update today fixes this issue. Applied update and resubmitted my return which has already been accepted. Verified before I filed that 4c was no longer checked incorrectly.
