Will my ex not get her refund if I owe the IRS on my amended filing?

[quenchware]

I accidentally claimed our son this year. Her return was rejected because of this. I've already filed my amended (1040X) to fix the mistake.Now that I don't get the deduction, I owe the IRS money. The question is; will my ex not get her refund until I've paid the full balance of what I owe to the IRS on this amended return?

I don't think this is the case, but I don't know. Thanks for any help you can give me.

Your child's other parent will not be able to e-file a 2018 return since you already used the child's SSN on your own return.  It takes so long for an amended return to be processed that e-filing will be impossible for her; but she can print, sign and mail the return that claims the child and it should be fine.  Your tax owed does not affect her refund.
