My Foreign rental income (Sch E) is not added to by overall income. Turbotax bug?

You should be able to see:

• You have a schedule E 
• Schedule 1 line 5 show the rental income. 
• 1040 line 10 does show sch 1
• QBI is showing on 1040 line 13.

That really doesn't make sense for a rental to vanish. Perhaps you have a data issue. A full or corrupted cache can cause problems in TurboTax, sometimes you need to clear your cache (that is, remove these temporary files).

Online version:

1. Delete the  rental, see How to Delete  
2. Log out of your return and try one or more of the following:
   • Don't use Internet Explorer.
   • Clear cache and cookies,
   • Sign in using a different browser.
   • Sign in using a different device.
3. Log back into your return.
   • Enter the information again.

Desktop version: 

1. Delete the rental
2. Save your return while closing the program.
3. Update the program
4. Open
5. Enter the information again.
