The closest distance at which the P900 will focus at 2000mm EFL is about 5 metres (16 feet).
I found that a +0.4 dioptre lens can reduce that distance to a range of from 1.6 to 2.4 metres.
The field width (magnification) of the P900 at 2000mm EFL with the Tokina lens varies only slightly across the focus range of about 1.6 to 2.4 metres. At a distance of 2.4 metres the field width at 2000mm EFL is 40mm and at 1.6 metres it is 37mm.
Below are a few example shots taken in the garden at various zoom settings up to 2000mm from a distance of about 2 metres (6 feet) with the +0.4D lens on my P900.
800mm EFL, 2 metres
850mm EFL, 2 metres
2000mm EFL, 2 metres
More details about the lens and more example images are given here .
