Thanks, @Lisa and @TaxGuyBill and other folks to me  always helpful.

First I filed MFS and his daughter student under 24, she already filed as single and she was not  dependent for the client.

Now that I am going to paper file because of changing status 1040-X for client, E-filing for her daughter now is available as a dependent by 1040-X. ( single independent to single as a dependent)

can I E-file for daughter for today (before the IRS begins shot down E-filing) and for some reason paper file for the client by 3-4 weeks later, he is out of the country.
