My w2 has code 12 DD . What is it for and how does it affect my taxes. I could not find this in to the my turbotax software. Can some one help.

I had filed for my mom a green card last year. Can I deduct her GC application processing fees. She also had moved from in year Nov 2011 . I did not clain her as she did not have her green card. Since she has a green card can I deduct her moving expense.

Please advice.

thanks
A
