Rejected e-file IND-512-01 (Dependent SSN) must not match another return

[sammeh]

Hi,

I filed 2018 tax return the exact same way as 2017 except one mistake that may have caused the federal tax return to be rejected by IRS. I submitted the state tax return through Illinois tax revenue online first, then I submitted the federal tax return through Turbo Tax afterwards. This may have confused IRS system and it is now saying that my spouse's SSN is matching another return.

Has anyone experienced this in the past?

To successfully efile the IL return you had to successfully efile the federal return FIRST ... so you could not have just filed the IL return.  So you accidentally filed the federal return already so did you get the original federal refund yet ?
