Other 1099 forms are imported correctly. View Details for the 1099B does show the form data, but when I click import, it doesn't import into TurboTax - it's not visible in the list of imported forms, nor is the data reflected in my tax calculation
If you are using TurboTax Online, try importing using a different browser.
See the following TurboTax Help articles for potential fixes:
This is with the Destkop verson of TurboTax. This seems like an issue parsing the 1099B form, because TurboTax successfully download the text, but could not import it.
For Merrill, I saw another user changed their password for Merrill and then was able to import. Let me know if that works for you.
User solution:
The ultimate solution, although I do not understand why, was to change my Merrill password. Once I did this, the import worked fine. My previous password worked in Merrill, but for some unknown reason when I used the same ID/Password in TurboTax, I could not log in.. Simply changing my password in my Merrill account and then attempting the import with the new password worked.
