Get your taxes done using TurboTax

I was able to clear the entry.  Hopefully, the tax return will transmit, as well.

In TurboTax Online, I manually entered an IRS form 1099-B transaction.  Box 1e Cost or other basis is left blank with the box checked The cost basis is incorrect or missing on my 1099-B.  

The Actual cost basis was entered at the screen We noticed there's an issue with your cost basis after selecting the box I know my cost basis and need to make an adjustment.

I select Review and arrive at the screen Take a moment to review these investments.

Select Continue and I receive a message that errors have been cleared.  IRS form 8949 reports the correct entry.
