Thank you for the reply. Follow up question, last year I had to do it by hand and mail in the injured spouse form. This year I would like to included it in my taxes when I file via turbo tax. How do I find this form and at what stage of filing does it go under? I just want to make sure I file everything correctly this year some my taxes go smooth and my refund is on time.
