Retirement tax questions

I don't understand any of this W-4P withholding stuff. I use turbotax to determine my income tax and What should be deducted etc? Honestly; I already put all this information in my 2022 taxes. Now I've got to go back

into my taxes and figure out what goes where on this new form? It's a little much for me. I don't know who to ask

or what to ask.
