I can't get any info on my stimulus check, I am disabled and have not filed taxes since 2017 6/15/2020 No check yet? Help please?

I was told I didn't need to do anything that it should come when I get my disability ck, I get it the 3rd wed of the month and didn't get anything, my fiancé is on ssi and disabled and hasn't got his either, we both have bank accts, he never had a bank acct till 2 months ago when I opened him a joint bank acct and I have another acct with another bank that I have had for 20 yrs, no direct dep, no check or card in mail, we can't talk to a live person, needing the money badly, thank you
