Hi Julian,
I'm having same issue with TurboTax product! Right after I posted mine, I saw yours. This is definitely a major defect, in my case, TurboTax over-reports ~$65000 total gain, and the discrepancy seems to be the difference between "Total Wash Sales and Total Market Discount" is added to my total gain, those two values should be separately reported like 1099B Tax statement generated by Fidelity.
FYI: my post: "TurboTax Premier 2024 mishandle imported Total Wash Sales and Total Market Discount Data"
