Laymans terms for filing W2 and UserTesting earnings

Hi - 

 

Can someone please describe to me in laymans terms exactly what I need to do to file my taxes for 2021?

 

I work a full-time job and will receive my W-2 here in the next month or so. I also participate in UserTesting and Prolific Academic. Both of these sites do not provide tax documents, however they do pay me through PayPal. 

 

I need to know how to file all of my earnings (W-2 and the money I have made from these other sites). 

 

I usually file a 1040 EZ, however I believe I need to now file another document for my money earned through UserTesting and Prolific. Which means, I think I need to now pay for another version of TurboTax filing software?
