Deductions & credits

Turbotax is calculating that, based on your income, you would be entitled to a rebate of $199 IF you did not receive a stimulus.  Since you already received a stimulus of more than $199 (I think that's what you are saying) then you aren't entitled to an additional credit.  

You seem to have missed the question in Turbotax "tell us about the rebate you already received."  It would have looked something like this.
