Box 14 Code Z Error - Federal Return

US Govt employee issue: I'm getting an error code this year that I didn't get last year and the W2 is exactly the same in its categories. Box 14, Code Z.

 

Error is "income under a nonqualified deferred compensation plan that fails to satisfy section 409A."

 

This is not accurate, as it's a federal compensation plan for thousands of employees. It was recorded in exactly the same way last year (Box 14, Code Z) and the was no TurboTax error. MA state return shows no errors this year.

 

I need a workaround so that I can file electronically. If I remove the Z then it erases the figure. There's no way to override the code.

 

Help would be appreciated!
