Hi , So I donated plasma this year, but I didn't make over $500, do I still need to report this income?

Plasma donation is taxable income.  In TurboTax this is where you should report it:

Go to Federal Taxes then Wages & Income

Next, scroll down to Less Common Income and click on Miscellaneous Income. 

On the page that states " Let's work on any Miscellaneous Income, scroll down to Other reportable income. 

Then enter the cash that you received as well as a description
