My 2019 return was rejected for a problem with Form 8801 originating in the prior year. When will this fix be made by TurboTax? The error is Fdi_8801_ErrorHold

The corrected Form 8801 was expected to be released this past Friday (Release 20). It should be ready for you. 

You should delete the form in your return. When a corrected form is updated it is possible for some old calculations is still in the form. Deleting the form will allow only the corrected form to be loaded.

To delete a form off of your return you need to:

1. Select Tax Forms in the Black bar on the left side of the screen.
2. Select Tools from the drop down menu.
3. On the Tools Center Select Delete a form.
4. Locate the form on the list and select Delete.
5. You will be asked to confirm the deletion.
