You should be able to get this working with the following steps:

First share the sheet with the email/"service account id" associated with the service account.

Then you'll be able to access your sheet-backed table if you create a Client with the bigquery and drive scopes. (You might need to have domain-wide-delegation enabled on the service account).

scopes = ['https://www.googleapis.com/auth/bigquery', 'https://www.googleapis.com/auth/drive']

credentials = ServiceAccountCredentials.from_json_keyfile_name(
'', scopes=scopes)

# Instantiates a client
client = bigquery.Client(project = PROJECT, credentials = credentials)

bqQuery = client.run_sync_query(q)
bqQuery.run()
bqQuery.fetch_data()
