The same thing happened to me, and I've seen complaints in other forums. My husband and I received a total of $2800 in stimulus payments, and I had no intention of trying to get more via the Recovery Rebate Credit, but due to the way the questions were asked and answered, a claim for $2800 for the rebate credit was added to our return which I did not realize until we received a notice from the IRS today saying we owed $2800.
