after entering 1099-R information Turbo Tax indicates a needs review without specifying what is needed
There have been several updates that were implemented recently. First, I suggest updating your program to ensure you have the latest updates installed.
This can be done by logging into your desktop product. Select Online in the menu on the top, and then select Check for Updates.
If that does not update your program, you can also manually update your program.
If you are using TurboTax Online, the program should be automatically updated.
Once your program is updated, follow the steps in this link to get to the 1099-R input section.
