After you file

To enter the Foreign Interest Income you would:

1. First you would delete the Form 1099-Int in the software
2. Then enter the interest through other interest 

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.

You would enter your Interest Income 

1. Enter interest income other in the Search Magnifying Glass in the upper right hand corner of the screen.
2. Select Go to 1099-Int in the Blue box.

This might clear up the Form 8938 since you now have interest income on the return. I cannot guarantee this will correct the missing 8938.
