How to get more terms with the Series[] expansion of InverseErf[x] around x=1?
This is not strictly speaking an answer, but I thought I provide code that can be used to generate the kind of expansion that OP mentions. Perhaps it is useful for other people here.
I use $y$ as an ...

The right way to do this is to start with an ansatz (note that the OP has neglected to explicitly declare the y'[0] == 1 condition):
