After you file

Hello, I applied for ITIN for my wife and mailed it with my tax return.  I received a new ITIN number for my wife on April 22.  But still haven't processed my tax return yet.  It's been 8 weeks since getting ITIN number.  What is normal time for processing a tax return this year?  Do I have to mail a copy of ITIN number with a tax return with written COPY on it to Austin, TX?
