My son did not get a stimulus check, then got a $1400 credit when he filed. Later he got notification the IRS had amended his return canceling the $1400 credit, and left him with a very reduced return.
I had my son go through all his deposits as I helped him file his return to verify that he didn’t get any $1400 deposits or anything from Treasury or IRS other than 2020 tax refund.
My daughter had a $1400 direct deposit in 2021, my son hadn’t.
