Can any one help?  I did an amendment and I cannot get it efiled.

Error Detail:
Submission must not be a duplicate of a previously accepted submission.
Error Resolution:
This return was rejected by the IRS because a return for this taxpayer has already been electronically filed and accepted. Verify that the taxpayer's SSN or TIN has been accurately entered, and verify that the taxpayer has not already filed their return for the current tax year. If necessary, contact the IRS at 1-800-829-1040 for further guidance.

If you cannot resolve this problem, you will need to print and file this return by mail.
If you need to correct the tax return originally filed, you must file an Amended Return.
