@juk_mi , please give me a little time -- I am not familiar with US-Poland tax treaty -- need to study it a bit.
In the meantime can you tell me __ when did you enter US and with what visa? ; was this your first entry into the USA? ; the 1042-S was from the same employer as the W-2?; was this your first employment?; are you single or married and if married to whom ( US person / foreign person)?; anything else that you could think of
I will come back once I have gone through the treaty --- thank you
