I haven’t gotten the 700 check

You will have to ask the issuing entity what is going on ... no one here in the TT forum on income tax questions can answer that. 

No one can see your tax return or your information.  We do not know what "gas refund" you are talking about.  That must be some sort of state refund, though, so contact your state to ask about it.

Is it for California?  They are still going out. See if you qualify
