Whether the basis for your transactions were reported to the IRS, and whether the information on your 1099-B is accurate are two different issues. As to the first, Fidelity has represented to you, in writing, that basis was not reported. Thus, unless Fidelity should tell you otherwise, you should be able to reasonable rely on the information they have given you about basis reporting and report the transactions on your return as basis not reported.
Regarding the basis amount and the sale proceeds, you might consider comparing those numbers with the same numbers on your trade confirmations. If they match, then you have a reasonable basis to enter your 1099-B as is. Therefore, on your last screenshot you can check the box, None of these apply and continue through the rest of the application. However, if they don't match, the trade confirmations may likely take precedence over the Form 1099-B as the trade confirmations were prepared contemporaneously with the transaction in contrast to the Form 1099-B which was prepared much later in time. Here again, you might just check with Fidelity if you see a discrepancy and ask them which document--the 1099-B or the trade confirmation--is the more reliable document.
