I had same problem very frustrating. I think I entered some Zeroes on the 1040 worksheet by MISTAKE. I found possible SOLUTION that worked for me:
1. Open Form 1040/1040SR Wks
2. Scroll down to the TAX SMART WORKSHEET section
3. Go to entry for "Letter J Form 8621 tax deferral from line 9c . . ."
4. If it is "0" replace it using the Space Bar and SPACE over the entry. (I think Turbo Tax program sees the Zero and thinks you need to file a form even if it is zero). So it should be BLANK no entry at all - NO Numbers.
**Look for other zeros on the Tax Smart Worksheet and space over them as well if you don't have a form filled out! Seems Turbo Tax will see a zero with any Form reference and then will look for the Form. Hope that helps. Karl
