Sold timeshare in 2021 for a loss

I sold a timeshare in 2021 for a loss.  I received a 1099-S for this sale.  I entered to appropriate data into TurboTax Deluxe under Investment Income - Stocks, Mutual Funds, Bonds, Other.  At the end of the process, I discovered that TurboTax had filled out Form 8949 incorrectly and was treating the loss as deductible.  In my case, the loss is *not* deductible.  How can I fix this problem?
