Unable to file due to dependent's amended return not being finalized

[danolson115]

I did my dependent son's and my taxes again this year using TurboTax. I submitted my son's first, and when that was successful, I submitted mine. Mine was rejected because I did not check the box on my son's return saying that he could be claimed as a dependent by someone else. I requested an extension on my return, and I filed an amended return for him in April with the box checked to correct it. I am still unable to submit my return because of the same issue, and it's the extension deadline. Checking the IRS website, it says that my son's return was adjusted on 9/19, but the completion date isn't until 10/20, which is too late for me to file. What are my options? Calling the IRS has not been successful.

Waiting for your child's amended return to be processed was futile.    You will not be able to e-file your return this year with the duplicate use of their SSN.    Your own return that claims him must be printed, signed and mailed.

Some users have had success by doing this:

GET IP pin in order to e-file if your dependent’s SSN was claimed on another return
