The only thought I have is that you didn't do EXACTLY what I suggested that you do. That is, my thought is that you DIDN'T follow the path of simply correcting the basis from the $0 reported by the broker to 160 for the first trade and 340 for the second trade if your tax liability went up a "crazy amount." My guess would be that instead of simply correcting the basis you, instead, went into the RSU step by step interview, and did something wrong like, maybe, telling TurboTax about the SAME LOT VESTING twice, once for the sale of stock "for taxes" and then again for the sale of stock "for cash" and then telling TurboTax "No" when TurboTax came back with its own calculation of compensation created by the vesting and asked if this was the amount reported on the W-2. Of course that's just a guess as you've based your judgement on the "correctness" of the entry by focusing on the "Refund -O-Meter" instead of looking at WHAT CHANGED in your actual income tax return.
DELETE those trades.
Enter them exactly as they read off the 1099-B, bad basis and all.
Tick the box next to "This sale involves an employee stock plan (including ESPP) or an uncommon situation."
Click the radio button next to "My 1099-B has info I know isn't right, or it has extra info I need to add."
Tick the box next to "The Form 1099-B shows an incorrect cost basis."
On the page "Correcting Cost Basis from Form 1099-B" enter the correct basis in the box "Adjusted Cost Basis (if applicable)." For the first trade you'd type in "160" and on the second trade you'd type in "340".
That will add the missing amount of basis and TurboTax will show all this correctly on Form 8949.
