I filed my grand daughter however my stimulus check did not have her portion on it.

If your granddaughter was over the age of 16, she would not have been included.  If she was 16 or younger and should have been included we are not aware currently of any way to address the issue in the near term - however things are constantly changing. 

As of today, April 15, 2020, the only known way to reconcile advances of the credit that are not correct is to do so when you file your return for the 2020 tax year in 2021.  Of course, this is subject to change.
