If I was summoned for Jury Duty, spent the day while they selected the Jury, and wasn't selected, but got 6 dollars compensation, how would it affect my tax return?

Six dollars should not affect your tax return one way or the other, but you need to report the jury duty payment.

To enter, change or delete Jury Duty pay -

• Click on Federal Taxes (Personal using Home and Business)
• Click on Wages and Income (Personal Income using Home and Business)
• Click on I'll choose what I work on (if shown)
• Scroll down to Less Common Income
• On Jury Duty, click the start or update button

Or enter jury duty pay in the Search box located in the upper right of the program screen. Click on Jump to jury duty pay

If they send you any sort of document like a 1099 for the jury pay you have to enter it on your tax return.
