If they used the wrong address, then they would need to amend their return. However, unless they claimed your dependents, then it would not affect your tax return.
If they did claim your dependents, then you will need to print and mail your return as it will be rejected for duplicate use of a social security number. They will need to amend their return to remove the dependents, however, this will take quite a while so you won't be able to e-file.

I see on another post you mention it is your spouse that is also filing? If that is the case, NEITHER OF YOU can claim head of household.
