My Fix:
- In the very top menu (grey area in the top part of the turbo tax window) click on FORMS (far left side)
- Click 1040/1040SR Wks in the left menu
- Scroll on the form on the right side until you see line 10.a
- Enter the same amount for lines10.a and 10.b
- Line 10.c should auto fill
- Click EasyStep (top left corner of main navigation menu)
- Run Error Check again
This will remove the error when they do the final review
