The most common reason for this to occur for tax year 2019 is when a taxpayer has incorrectly filled out the nonfiler form for the economic impact payment ("stimulus check") previously.  

Other reasons can include being listed as a dependent of another taxpayer or, occasionally, identity theft. 

There is no workaround for this error.  The return must be printed and filed by mail.
