MA non-resident - reporting capital gains/losses as non-Massachusetts

[picard17011701]

I am a Massachusetts nonresident with rental property income in the state.  I also trade stocks (not as a business).  I noticed when completing my MA taxes that all of my capital gains/losses transactions are treated by Turbotax as MA transactions (and subject to MA income tax) unless I designate each transaction as "Non-Massachusetts source."

This is very tedious, as I have hundreds of transactions from last year.  Is there any way to designate ALL of my stock transactions as non-Massachusetts at one time?  Thanks!

Did you ever discover a solution for this? I have had to endure this problem every year.
