Duplicate SSN error. I think it's because I originally signed up as nonfiler for stimulus, as my income didn't require me to file. I need to file. How do I fix this?

When using the non-filer system on the IRS website, your information is processed by the IRS as an original filed return. 

Any subsequent filing submitted electronically will be rejected and must be mailed to the IRS for processing. 

You can do this in a couple of different ways: 

• You can create and file an amended return with Form 1040X, which will be processed by the IRS as an amended return. 
• Or, you can complete your Form 1040 information using TurboTax and include a cover letter with the return to explain that you completed the non-filer registration for the stimulus check and that this is your correct tax return.  Instead of the cover letter, you can also write '1040X Amended Return' on the top of your Form 1040 before you sign and mail it.

Don't forget that when you mail a paper return to the IRS, you must include copies of your W-2s and 1099s, plus you need to sign and date the return.  

Internal Revenue Manual 21.5.3.4 General Claims procedures states that ‘an informal written inquiry that includes everything necessary to input a correct adjustment’ will be processed.

This is the issue I am trying to fix.  I originally signed up as a nonfiler for stimulus in April.

I tried to file my taxes today and there was a duplicate SSN error.  So I am learning I need to do something with 

a 1040x -- can I add that to what I have already done on-line?  How do I do that?

I have the same issue and now I’m scrambling trying to figure it out. 

From what I understand you can through TurboTax . But you’ll have to print the paperwork and mail it in And make a cover page where you explain that you filed “Non-filer” for the stimulus check but that you’re now sending your most current and correct tax return, or in no cover letter page you can just write on the top of your 1040 “1040X Amendment Return “ before signing it and mailing it. 

It also states,

“Don't forget that when you mail a paper return to the IRS, you must include copies of your W-2s and 1099s, plus you need to sign and date the return”
