1099-B Box E

Mongoose — Mon, 16 Mar 2026 02:51:07 GMT

2025 tax year. I imported final 1099-B info in CSV format into TurboTax via the Fidelity Investments website. All information from the Fidelity 1099-B appears to have been imported fine. I even see Box E transactions in a Copy#2 of a Capital Asset Sales Entry Worksheet. This information (Box E) also appears on the respective "Capital Asset Sales Worksheet" in the appropriate section above the text " Long term sales with cost basis NOT reported to the IRS". All appears well s far except that the values seen are NOT propagated to Schedule D Line 9 items d, e, and h. What gives? I have found no where else where the involved loss is reported. Am I missing something? Looks like a bug to me right now as all appears well for Box A and Box D items from the 1099-B...just Box E with the problem.

That means that there's no cost basis for those transactions on the Form 1099-B that you received that also goes to the IRS, so you have to enter your cost basis manually for those transactions. To enter your cost basis:

Select Federal Taxes
Select Wages & Income
Select Edit next to the 1099-B from Fidelity
Follow the prompts to enter the original cost (and any cost basis adjustments) of the securities you sold listed under section E.
