Getting 'C11 - The value recorded for the element is an invalid number string for a U.S. TIN." - Check my SSN and Name is matching with IRD record

@mduntoor has your name changed recently? (divorce, marriage, etc?)

otherwise, go back and re-key your SSN and your last name.  The first four letters of your last name and the SSN have to match EXACTLY to IRS database. 

if still no luck, paper file.
