Deductions & credits

my federal return came back as incorrect because of the recovery rebate credit. i remember being asked about the stimulus payments in the return and replied yes to getting both last year, but somewhere down the line i must've answered something wrong thereafter. Not sure. I don't remember. But i do understand not to receive extra stimulus money that i already got. i always try to answer questions as accurate as i can. Anyways Turbo Tax had an extra $600 added to my return when not supposed to.
