R0000-058-01 - An XML document that represents a binary attachment must have a valid reference to an attached file.

What type of attachment did you have on your return?

Only attachments we had was the recommended upload of W2's and 1099 in PDF format.

Deleted and re-entered manually. 

Just resubmitted.

TurboTax didn't explain where to correct the errors the IRS discovered.  TurboTax review never found the problem and said return was ready to go.

We will see if this was the fix.
