I called Intuit today (March 15), and (after a short 7-minute wait) spoke with one of their Help Team Members. He confirmed that Intuit is aware of this issue, and TurboTax will receive an update later today that will correct this bug.
I asked if it would be necessary to delete the existing 1099 data and the associated Capital Gain (Loss) Adjustments Worksheets, and he said that the fix will automatically remove the Capital Gain (Loss) Adjustments Worksheets and will restore the 1099 info to its proper places.
I might create a new TurboTax file any way, so I can compare results...
