Solo401K-Calculation in TT and Catch-up

I enter my solo-401K and I do not see it reduce my tax burden after it is entered.

does it only process after I complete my entire tax?

 

secondly with catchups; say I contributed 19000 and an additional 6000 in catchup.

do I enter 25000 in employee deferrals? or o I enter 19000 and 6000?

My issue is with the turbotax and entering the information and not with the tax law.
