It depends what the second check was actually for. You indicated that it was also wages, or income which may mean it was extra earnings not originally included. Follow the instructions about how to enter it and then the missing information may go away.
If it was for earnings like wages, then it must be reported like self employment because of the form it was reported on - 1099-NEC,.
If you believe this is not self employment income, meaning it was not for a service you performed, then you can enter it as a legal settlement. Read more details in your settlement documents to be sure.
