They all look like corporations so you need to check the EFIN box and it will go away.

Doesn't it require first and last names to match the social security numbers.  Looks like all of your numbers are social security numbers not FEIN's.

YOU HAVE JUST POSTED INDIVIDUAL'S SSN ON A PUBLIC FORUM!  I am having the same issue though!

I've redacted the image to remove the personal details.

Good job :-)

Aatrix put instructions out there, for how to cut and paste the info into those first name/last name fields manually, which took me about and hour and a half for 300 1099's.  The processing fee I paid to Aatrix was over $600.  Severely disappointed and looking for a new way to do these next year, as this is not professional or effective. Aatrix also dropped the "email" field and it's empty. So, I either don't use the email feature and just have them US mailed, or I do a whole bunch more copy and paste.
