Turbo Tax says I contributed too much to Roth. Earned income from W-2 is $4,682 & 1099-NEC is $2,000. Combined $6682 is my Roth contribution. Why $142 too much?

For your earned income from self-employment, you have to subtract the company portion of self-employment tax. As you may know, if you are an employee, your employer pays one half of your social security tax. It is similar with a self-employed person, half of the self-employment tax is paid by the company, so that portion needs to be subtracted from your net  income listed on your schedule C. Since self employment tax is not listed on your Schedule C, it has to be subtracted from the net income on Schedule C to determine your earned income.

As ThomasM125 indicated, $142 is the deductible portion of your self-employment taxes and that portion will not support a retirement contribution.
