1040-X "Explanation of Changes" - How specific to be?

I already filed & received a refund, and am now filing an amended return.

 

On Form 1040-X, there is a a section "Part III: Explanation of Changes" with a paragraph-sized space of blank lines...

 

I'm wondering how specific, or general, to be here?

I made one large change worth ~$10k, and a handful of very small changes. Should I list everything I changed? Or just focus on the big one? 

 

Any tips appreciated.

Thanks,

-Daniel
