It is not a formal dictionary word, except that it is listed in Wiktionary as one word stepgrandmother.

Conversely, Wikipedia lists it as hyphenated step-grandmother, and multiple sources list the term step-grandparent. The consensus, therefore, would be to hyphenate it in that manner.

The words stepmother and stepchild are not hyphenated.
