Get your taxes done using TurboTax

It's the sequence of steps you are using. ‌Try this because it worked for me. 

1. Select open form. and Type in Form 1116
2. Once it appears on the screen as it is displayed, select it and then select open form. ‌You have created the first copy. Don't try to rename it. Now it is populated in your forms.
3. Now repeat step 1 again. 
4. Now go to create new copy.  You may call this Form 1116 (copy 2). Select add form
5. Now you should have both copies in your tax return using this method.

Here is a screenshot illustrating this. You would only generate this when you create the second copy using the steps I outlined above.
