OBBB with Standard Deduction

I am using TurboTax online which gives running calculation of expected return. The standard deduct is applied but not the OBBB. The answers thus far are not answering the issue. My expected return is NOT reduced by this $12000 OBBB. When I inputted no social security payments my return was about $5500. With social security payments included it was reduced to about $1600 so clearly this OBBB is not being credited under the standard deduct. I don't have any reason to itemize at this point in my life. WHERE is the OBBB being show? I should be getting a lot more money back than TurboTax is showing.
