If you had to file your federal return by mail, you will have to file the state by mail too. The state cannot be e-filed unless the federal was successfully e-filed. If you mailed the federal return, go ahead and mail the state. You do not have to wait for the IRS to approve of a mailed return in order to mail the state.
Have you mailed your federal return yet? It will not help you to wait for someone else to amend, etc. if there was duplicate use of a SSN. The only way for you to file is to file by mail and let the IRS sort out the duplicate use of the SSN.
