Rejected:"The Primary SSN in the Return Header has been locked because SSA records indicate the number belongs to a deceased individual." How do I correct the "header"?

This is the first return just in my name after my husband passed away in 2017. 

I removed his data from the old return's personal section, but the return was still rejected: The Primary SSN in the Return Header has been locked because Social Security Administration records indicate the number belongs to a deceased individual. 

How do I correct the "header" of the return?
