While @Rick19744 is technically correct, it is unlikely the gym management will correct the 1099-MISC and send a proper 1099-NEC.

Enter the 1099-MISC in the Schedule C (Self-employment income) interview - it is not necessary to have a 1099-NEC to report self-employment income.

Enter "schedule c" in the Search Box and select "Jump to schedule c" from the results. This will start the Schedule C interview.

The following screenshots show what to look for in making this entry. When you select the "Add Income for this Work" option, the next screen allows you to identify and report the 1099-MISC income.
