After you file

I have not received any of the stimulus checks.  I am unemployed in a nursing home and have been for 2 years.  I am waiting on SSI approval. I e-filed specifically to get the recovery rebate credit and it said my federal return was accepted and I'm getting 1,800.  However, my state return was rejected.  I tried to fix it, but I got a message saying that if I am just filing to get the RRC, then I don't have to do anything with my state return as it doe not effect my federal payment.  Is that true?
