Signature needed, MFJ, spouse deceased

We're trying to e-file a 1040 (and NY return), MFJ, spouse deceased. 

 

On the Review Your Federal Filing Choices page, it says "Signature e-filing PIN or Date of Birth Needed".  When I click edit, it shows a PIN, date of birth and today's date for the surviving spouse and nothing for the deceased spouse (no heading, as opposed to heading with blank entries). All of the other items look correct. There is no Continue button at the bottom of the page.

 

What signature, etc. is it looking for and how do we e-file?
