Get your taxes done using TurboTax

ask Robinhood the reason. This is not the norm and I don't know if this will be red-flagged by Turbotax preventing e-filing.  This can also cause issues with the IRS because if that negative is not acceptable to Turbotax (you would then need to enter it as a positive in the cost column), the IRS record of total proceeds won't agree with your return.
