Where do I add income that I received from being a pollworker? I did not receive a W-2 or 1099.

You can report it under Miscellaneous Income:

• Select Federal, then Wages & Income.
• Scroll  down to  "Less Common Income," 
• Click  Start or Revisit next to "Miscellaneous Income, 1099-A, 1099-C."
• Click  Start or Revisit next to "Other income not already reported on a Form W-2 or Form 1099."
• The next screen "Did you receive any other wages?" Select Yes and Continue.
• The next three screens are for household employee wages, sick or disability pay, and Medicaid waiver payments. Just click Continue on those three screens without entering anything.
• On the screen "Did you earn any other wages?" Select Yes and Continue.
• The next screen, select Other and click Continue.
• On the next screen, "Any Other Earned Income," enter a description and enter the amount you were paid.
