This is a MESS. I'm in the same boat. My case is a bit different, PayPal sent me a 1099-K for a 2021 sale I had already paid taxes for back in 2022. But I only transferred the funds to my bank account in 2022 and that triggered a 1099-K. Since I already paid tax on this in a prior year I need to cancel out the 1099-K with line 24z AS PER THE IRS.
Add this to the long list of unsupported stuff by TurboTax...
