Thanks for your response.  That confirms my understanding that on Resident 1040 side there is no separate and / or exclusive and / or dedicated way to exclude such treaty income similar to what the ProSeries provides for Social Security Benefits exclusion for Canada.

Yes, Sch 1 Other Income provides a work around solution which is a great suggestion by you.  But I don't know whether we need to grab Sch OI from 1040-NR Item L and attach to Sch 1 of 1040 Resident.  That is not only more work but may confuse the IRS seeing Sch OI of NR being sent with 1040 Resident.  

But I accept what you have suggested is a very good solution and accept as Best Answer.

Thanks.
