Yes, it is a bit tricky with how the IRS changed the verbiage. If you think about the timing, however, of original receipt of the payment - last Spring for the first one - the "idea" is that everyone would put some or all of that back into the community. Hence why they chose to call it "stimulus payment". Now, if you did not receive it and should have, this is when the call it a "recovery rebate". I have yet to see anyone get "dinged" however for tax debt. Child support, I am not really sure. I would check on that to be certain that is, in fact, why you got less.
