Is there a correct way to fill out new W4P based on same status as old W4. Allowance word not there, dependent is. I had a flat rate, how do I fill this out the same way?

There is no way on the new form to have a flat rate ... does your pension plan not give you that as an option to check ?   Or are they requiring the W-4P ?   If so click on Married and hand it in and see what amount is withheld.  Then if it is not enough you can choose single  and/or  enter the missing amount on line 4C.    Review the withholding tables for monthly payments on pages 21 - 23 ... that may help you decide which filing status to claim and if you will need more on line 4c to get you to the amount you desire ...  https://www.irs.gov/pub/irs-pdf/p15t.pdf    FYI ... the filing status on the return doesn't need to be the same as the W-4.

Although, you cannot select a flat rate, you can choose an exact dollar amount.  See Line 4c:

2022 Form W-4P (irs.gov)

Ok, after a quick read of the publication referred by Critter, plus what you sent: I complete step 1 name address etc, status. Skip 2 and 3, and put the amount I want to be withheld in 4c, and that's it ? What I am missing is why the line (c) Extra Withholding, says after it "Enter any additional tax you want withheld from each payment ? That would imply that something prior will cause an amount to be withheld. If nothing is filled in except my Step 1 info, and the 4c amount, why is this ?

Thanks,

Steve

Talk to the retirement plan administrator to get this done the way they want it done and how you get the desired withholding.
