Deductions & credits

Hi, I am searching for the option" I choose not to use credit from prior years" but no success.  Rather, when I did interview questions, I got this question" Did you pay foreign TAX in 2021 or have credit to use from prior year?" For this question, I have to answer " YES" ( because I have paid foreign TAX in 2021) .  I guess this would carry over my prior years credit and I cannot avoid 1116 schB.  I am wondering if I override1116 ln 10 to zero, like some people suggested in previous posts, what would happen to my carry over credit, do I loose them all? or can I still use them next season? Also I wonder why we get different interview questions. thanks
