Yes. The line number 10 on their tax return is 0 and both of them marked the box that someone could claim them. My brother has claimed my dad and I have claimed my mom since we both are supporting one of them. But e-file was rejected with the error message above. So I'm assuming that I need to mail my tax return instead of e-file. Is that right? Or should I e-file it one more time? Thank you!
