Retirement tax questions

I get that the 1099 NEC is a new thing.  But this is the first year TT has tied 1099s from the Personal section to the Business section.

Furthermore, why would it attempt to distinguish between 1099 NECs entered in the Business Income section vs Personal Income section if it's going to tie them together anyway.  Why would it tell me to go to the Business section to enter a 1099 that's related to a business if it's just going to tie it to a business?  It seems like a either a bug, or bad interface design.
