W2 from work done in a prior year

Hello all,

 

Sometime last year (2020) I received a letter in the mail about a job that I did in 2015 delivering phone books.  The letter stated something to the effect of, the company was caught underpaying its independent contractors.  So I naturally said, hey free money sure I'll take it.  So I did what the letter told me to do, and a month or two later I received a check for $58.  I was pleasantly surprised when it showed up.

 

Two days ago I received a W2 from that company stating I made $58 in 2020.  So the ultimate questions is: Do I have to claim this on my taxes?  I ask because the work was done in 2015 so do I have to report it in 2020?  Also, I thought that if you made less than $xxx.xx (might be $600), there was no requirement to send a W2.  Little confused on what to do with it, I believe it shouldn't have to be reported but also don't want to throw a red flag for IRS to audit me.  

 

Thanks for any advice in advance.

 

Jack
