Hello and welcome Dean. Have you looked at general purpose inexpensive probes as shown at Banggood and Aliexpress?

It is likely that there is a label on the panel below the BNC connectors that mentions something like 1Mohm 13 pF (from my Rigol DS1054Z) which is the standard input impedance. Any 1 Mohm X1 probe will work.
Like these:

Or you can buy far better probes at ProbeMaster.

FWIW, the probes I linked will have a switch to choose between 1x and 10x. The probe compensation adjustment applies only to the x10 range.
Some scopes have a selector to choose between 1X and 10X since 10X clearly affects the display (1/10 as big) and any displayed values will be off by a factor of 10.
There is a long scope tutorial linked to the start of this forum. The creator, w2aew, works (worked) for Tektronix and he really knows about scopes. He has a lot of introductory level videos and all are excellent. Google for w2aew, I suppose...
I like his op amp and transistor videos. Dave has some good videos in that arena as well.
