Good afternoon everyone hope all is well. So I killed Code P0420 upon using Seafoam Intake Cleaner now the check engine light came back on showing as Code P0456. What location do I need to find to fix that small leak?

Replace the fuel cap. If that doesn't fix the problem you may need to perform a smoke test but first do a visual inspection of the evap system lines. (Always go for the low-hanging fruit first.)
