The header is missing is referring to your upload. The columns do not have titles.
For more information, see:
I didn't receive a 1099-MISC, 1099-B, or 1099-K for my Bitcoin or other cryptocurrency earnings, do I have to report them?

The columns do have titles and all other data is also present. Still continue to get the error.
Any thoughts?
