Business & farm

I am using Desktop version. but
1. I can't edit any of those numbers on 8829 & Worksheet. How do I do that?
    Also, where/which line numbers do I change those? I am looking line 30, which comes from line 42. I can't modify line 42 either.
2. Do I need only single 8829 & Worksheet? I have them on both of us now.
3.
