Where do i report income where a 1099 is not generated because it was under 600

If you want to report cash with no documentation, such as a W-2 or 1099-MISC,

• Click Federal Taxes > Wages & Income
• Scroll down to Less Common Income
• Go to the last selection, Miscellaneous Income and click Start
• Go to the last option, Other reportable income and click Start
• Answer Yes to Did you receive any other taxable income?
• Enter the description and then the amount.

I can make this entry, but it doesn't show up as earned income, so it shows an over contribution to Roth IRA.
