3468 FORM

Deleting the form from your return should solve this problem. Look for both Forms 3468 and 3800.

If you are using the Desktop version of our software (CD/Download):

1. Click on Forms in the upper right of your screen
2. Find the relevant form on the left hand side of your screen in the Forms in My Return list
3. Click on the form (note, there may be one for both taxpayer and spouse if married filing jointly)
4. Click Delete Form button at the bottom of the screen
5. Click Yes to confirm you want to delete

If you are using TurboTax Online:

1. Login to TurboTax and click on Continue your return to get into the prep section
2. Click on My Account at the top of your screen
3. Click on Tools 
4. In the list at the bottom, click on Delete a form 
5. Click Delete next to the relevant form
6. Click Delete Selected Form to confirm deletion

The incorrect identification of Box 20 Code AG/AJ will be addressed in a forthcoming update. We recommend signing up to be notified when the update is released: Why am I receiving an error in TurboTax for Schedule K-1 Box 20 when code AJ is selected?

However, since this information will be used only if your net losses from all businesses are more than $289,000 ($578,000 if filing a joint return), you have the option to omit the code and the amount(s) from Schedule K-1.

I have same issue. Really annoying
