I just filled our 2018 tax extension, but my wife's name and SSN was not included on the extension? Joint return, I added her on the form, but she was not included?

If you are filing married filing jointly, your extension will cover her. Your approved extension will cover both of you.

Form 4868 only includes the name and SSN of the primary taxpayer (the one listed first on the return).
