No. Please make sure that the first four letters of your last names match up with what Social Security has for you, as well as any Jr, Sr, etc. Perhaps there is a name change that has not been updated from the Social Security Administration to the Internal Revenue Service.
Otherwise, unfortunately, there could be an identity theft issue. It would be in your best interest to contact all three of the major credit bureaus to place a fraud alert on your credit records. (see Publication 5027, Identity Theft Information for Taxpayers for direct links that will help)
The section of the article referenced is regarding registration for a stimulus payment is in reference to last year's filings that were due July 15, 2019.
By registering for a stimulus payment, that would mean that you had identified as a non-filer with the IRS on their site. This is different from receiving your payment automatically based on 2018 tax year calculations.
