Difference between first tier and second tier distribution from trust

An earlier discussion comment said

Tier 1 distributions are distributions of current income that are required to be made according to the terms of the governing instrument and the applicable local law (whether actually made or not).

Tier 2 distributions are any other amounts paid, credited, or required to be distributed (and actually distributed).

I'm confused:

TTax says the account income is $1,107. This appears to be qualified dividends minus Section 199a dividends minus interest.
However, the capital gain on 1099 is $4,070, which I've assigned to the beneficiary.
Total actual distribution is $5,000.

What are the correct Tier 1 and Tier 2 entries?
