I asked your question to the Payroll. Copying the reply they gave to me about the 8000$ one i.e. the tax treaty:
"
The 1042-S with the $8,000 is the treaty benefit.
This was reported to the IRS and will need added to the tax return."
The problem is whenever I add this 8000 to my amended return it shows I am due instead of getting any refund. I had tax treaty on previous years too, but I never was due.
