I’m not following this comment. If the taxpayer who originally posted the question is the person who needs to remove the child as a dependent, that amendment should be allowable electronically. The other taxpayer who needs to include the child is probably blocked from e-filing and needs to file by mail, but I would not attach any other written documentation. The IRS will process the refund as-is. It takes the IRS 9 to 12 months to start an investigation of a duplicate dependent claim, and by that time the amended return will be processed and any conflict in the system will have cleared. (It’s just that the conflict won’t clear in time to allow the other parent to e-file.)
I am more concerned that if this taxpayer needs to remove their dependent, because the other parent is claiming the child, I want to make sure that the taxpayer adjusts the dependent status in the correct way, so they are not deprived of the ability to claim EIC, head of household, or the dependent care credit, because those benefits always stay with the parent who had custody more than half the year and can’t be released, transferred, or shared.
