After you file

Thanks for the reply. I filed on 4/17/20 and the filings were accepted on 4/19/20. I already received my federal and state return. It really doesn't make any sense to me. So if they go by my 2018 return and lets supposed that in 2018 I qualified then therefore they would send me a check? but lets say that I filed my 2019 return today and I don't qualify for some reason or another. does that mean that they would tell me to give the money back? thanks for the reply.
