Desktop Mac Error on Form 8949

I get the following error after entering my stock sales transactions: "Form 1099-B Worksheet (Fidelity Investments)--Capital Asset Sales Wksht (1): Salecat: Form 8949 Check Box has an invalid selection for . "C" or "F" are the only valid selections for a worksheet with transactions not reported to the IRS.

 

Issue, I am inputting via the Form exactly what is on the 1099-B.  My 1099-B says Short term transactions for which basis is NOT reported to the IRS.

 

So from the Turbotax form I choose  NOT REPORTED to IRS but get above error.  Am I interpreting this wrong?
