Looking to (Name-matches ) for file name with " space(1)"

I have some file names I am trying to match. An example of the file name is
IMG_20180531_0001 (1).jepg I really just want to match any file name which has (1) in it.
I have tried a number of combinations like
ab12%? %?@
ab12a1%(
but no joy I must be close but no cigar ?
Thanks Rik
