The readout showed 20k km/hour towards the end. It was definitely near orbital speed.

You might be looking at the first stage’s data.

Edit: 24,124 km/hr when telemetry stopped on the stream; 15k mph.

A 'k km' is an Mm, so 24 Mm/h , (or 6.67 km/s , if you'd like to go full SI)

Technically correct but not really clear of it helps clear communication in this context. SI natives think of a "kilometre" as its own thing (in the same way one thinks about a "mile") rather than thinking about it as a thousandfold multiple of a metre.
