MA non-resident: lines a and b (total federal..) are correct, line 14 e (non-mass inc.) is not correct. It is exactly twice as much as it should be. How fix in turbotax?

In TurboTax final federal forms are all good. for MA-nonresident, it copies most values from federal correctly but line 14e (non-mass source income) is exactly twice as much as it should be. Where could this come from? How can I fix this in the online turbo tax? I tried re-entering all state information, but nothing changes.

OK, problem was in State return one gets asked if any salary on W2 came from outside state, here I should have entered 0 as all my out-of-state salary came from another country and is not on any W2 form. The only W2 is from that state. Instead I had incorrectly entered the foreign income here and so it was used twice in the computation of the out-of-state portion of my total income. 

The question on that page should be more specific to avoid this confusion in the future. 

Hope this helps someone else.
