State tax filing

Thank you for your response.  Yes we are filing the Massachusetts non-resident return for my spouse (because we do not live there but her company is there), married filing separately.  We filed the federal return married filing jointly and have a joint AGI.

The Massachusetts return is now asking for my individual AGI.  The blacked out annotations in the image refers to me.

How do I find out what my AGI is when we filed jointly?  Should I make a mock married filing separately return for myself and use that number?

Thanks
