Hi MarilynG1 - thanks for your response.
I'm not sure TurboTax automatically calculates my non-Maryland income - if I leave this field blank, TurboTax says I owe tens of thousands in unpaid taxes, as though my entire income for the year was taxable for Maryland (it is not).
So while I also would have assumed TurboTax automatically calculates this for me, I am fairly sure I do need to put a number in here. The question is, how do I calculate that number, without wading into Maryland state tax form 502 myself (again, the point of TurboTax is that I don't have to file these forms myself...)?
