I thought the internal clock was 8MHz, but I wasn't sure.  I changed
the sim setting around until it seemed to blink at the same speed as
on the chip, to check what speed it was running at.  It turned out to
be running at 31.25KHz, quite near to 20Hz.

I now fixed this - I didn't know to change OSCCON

all working now
