The return I filed today on TurboTax was rejected by the IRS because it was seen as a duplicate. My original 1040, which I did through the new IRS portal was rejected.

I sent in a 1040X through the mail, but got a letter from the IRS saying "we are unable ot read the 1040X." So, I submitted via TurboTax today, but I've gotten a rejection because "the Primary taxpayer's identification number assigned to this return has already been filed. How do I resolve this?

It is not clear what all you have done--or are trying to do.   If your original Form 1040 was rejected, then you have not filed a tax return.  You do not "amend" a rejected tax return.  Amending --using a 1040X -- is only done if you have already filed a tax return and it has been processed by the IRS, and then you realize you need to add information or correct something.  Amending is not the process for fixing a rejected return.    

If your original Form 1040 was rejected when you tried to e-file it, then you can file it by mail instead---print it, sign and date it in ink, and mail it in.   

But...first....please explain in detail---and in sequential order----what you have done.

When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s.  Use a mailing service that will track it, such as certified mail so you will know the IRS/state received the return.

Federal and state returns must be in separate envelopes and they are mailed to different addresses.  Read the mailing instructions that print with your tax return carefully so you mail them to the right addresses.
