Schedule C Error?

I have a single 1099-NEC for $600 that needs to be entered into Schedule.  Turbotax populates that information in two places, "Gross Receipts or Sales NOT Reported on a 1099-NEC or 1099-MISC" and also on "Enter Gross Receipts or Sales Reported on a 1099-NEC." Because it shows up twice, I end up with $1200 total rather than $600.  Is this an error?  If so, how can I fix it?  This will presumably result in me being charged more in taxes.
