If your spouse prepared a correct joint return will all of the income for both of you on it, then the two of you are done.   Do NOT mail the return you worked on.  As long as you did not mail it, it is like it does not exist to the IRS.  And since she e-filed already using your SSN, you cannot e-file it --it would be rejected.  When you file a joint return, there is only ONE return that has all the information on it for both spouses.  Make sure she included your income on the return she filed.

If you want to clear your own:

Hello Dear, 

Thanks for Your Reply , But I can not find the clear and start over as you have mentioned.

The problem is , I have already processed the return and now it is pending on "Fedral Retrun Ready for Mail" So I am unable to make changes except through amendment which is through mail .. I think .

Is there any way back ?.

Thanks.
