Until turbotax resolve the negative sale proceeds, I edit the "Sales Proceeds" and "Cost or other basis" fields.
Go to Federal Taxes --> Wages & Income --> Stocks, Mutual Funds, Bonds, Other.
Click on Edit "broker", for mine it's TD Ameritrade Clearing.
Find the negative Gross Proceeds, click on Edit.
Change "Box 1d Sale proceeds" field to 0 and change the "Box 1e Cost or other basis" to the positive of the "Box 1d Sale proceeds".
ie Before Box 1d: -248.35 Box 1e: 0.00 After: Box 1d: 0.00 Box 1e: 248.35
The end results for Federal Tax Due and "State" Tax Due" should be the same.
