To assist you with your question, was the EIN correction made before or after you have efile your tax return? If you have already efile your return before the correction was made, you will need to wait for your return to be either "Accepted" or "Rejected" before making any changes. 

If you have not efile or got "Rejected" and made the correction, then you should still be able to efile your return. If you corrected the information and resubmit the e-file and it continues to reject, then the name or EIN for an employer on your W-2 or 1099-MISC doesn't match IRS records, therefore you would have to contact your employer.

To make the correction on your tax return after it was "Accepted." Then, you must amend your return via using the mail filing method. To amend your return, please follow the following instruction for your tax year. https://ttlc.intuit.com/replies/3288565
