Received a 1099-Misc for a Settlement for back wages

I am self-employed now but used to work for an employer 5 years ago. There was a class action lawsuit of for back wages and and I received a settlement. I got a 1099-misc and a W-2 from the lawyer's office. I have amounts in Box 3 "Other Income" and Box 10 "Gross proceeds paid to an attorney".

 

TurboxTax says that there is a problem with my taxes and is asking for a "Link to Schedule C" for Box 10.  I have no idea what they are asking for and when I finally got to talk to someone at TurboTax after about a 2 hour wait, the guy's phone dropped the call.

 

This shouldn't be considered business income since it wasn't from my business so why is it asking me to link to a Schedule C. Also, how do I link to a Schedule C?

 

I really don't know what to do here and I hope someone can give me an answer.
