Here I thought that Black is lost, and wondered why Black moved now 99...d1Q.
Are there any others here who would have belived that black is lost?

Few moves later:

The bizarre magic of positions like these comes from 6 or less men on the board.
In fact, even when there are more than 6, an engine that is behind may try to reduce the board to 6 men so that a known draw position can be forced.

In my database of 33000 engine-engine games there were only 5 with a Queen vs 2 Knights position occurring.
2 of these were won by the side with the Queen. 2 were draws because the Queen was taken by a Knight on the next move in one game and was taken following a check forking King and Queen in the other.
The other game between List512 and Ivanhoe would have been a draw if I had had the KNNKQ tablebase files when the game was played in 2014. Although I had most of the common 5 man tablebases at the time, I did not aquire those ones until 2016.
In the position shown, List (which can use tablebases) played Nhg4 and lost. The only drawing move was Ne4+ according to tablebases.

What is black with 2 knights meant to do to draw?

According to the online 6 man tablebase site, Black has 6 other moves apart from d1=Q for a theoretical draw at move 99.
