Help getting Grandma her stimulus, should I amend a return?

I was asked by my mother to do my Sister's Taxes, she's never filed because she's severely handicapped however I successfully got her her stimulus money.

 

I was asked to do the same for my Grandmother, she's in her 80's, a resident and has never filed taxes before. I couldn't really report any income because she doesn't receive anything, i put in the relevant info but unfortunately she has not received any stimulus money. I have not gotten any email stating there was a problem either. I double checked her Taxes and fail to see an issue. I thought perhaps her being a resident could effect things but I come too learn that should NOT be a problem.  I'm not sure what I should do, I want to amend her taxes but don't know where exactly I could make changes to fix something if anything. Is there a resource I can use besides amending her taxes?
