@ColeenD3 Thank you very much! This is very helpful.
I have two a follow-up questions.
I am a resident alien for tax purposes. I am filing my taxes jointly with my wife and she does not have SSN/ITIN. I am sending my federal return with W-7 for ITIN to the Austin location listed in ITIN form. Do I need to do anything special with respect to my wife's ITIN for my 511NR for Oklahoma? Can I just send the printed federal return copy along with my Oklahoma 511NR without my wife's ITIN?
