So how come 1830 1-4 interaction? There should be 57 of 1-4 interactions....


Mark already told you this - interactions that exist are different from possible interactions. You may have 57 interactions, but that's specific to your system because of how many atoms there are (which is also independent of how many atom types are used therein). grompp generates a bunch of information (a matrix of possible interactions that could theoretically occur with N atom types); whether or not it uses that information is not necessarily relevant.
