Ok thank you for your help.

Where can I get the form? I don't have a computer or printer. I use my smartphone

So do I have to amend my taxes or just send the form in?

Ok and will this get me back all or only part of the refund that was to be given from my income?. Because she had no income she doesn't technically have a share...

What if she has no W-2 or W-2G or 1099? She had nothing for any income what so ever only I did.
