Hi DLottcs,
To be accurate, you should submit a 2022 Form W-2P for all pensions/annuities.
Form W-4P Withholding Certificate for Periodic Pension or Annuity Payments
https://www.irs.gov/pub/irs-pdf/fw4p.pdf
Please see page 2, Example 2 for the largest pension; Example 3 for the smaller pensions.
Alternatively, you can use the most accurate way.
IRS Tax Withholding Estimator
https://www.irs.gov/individuals/tax-withholding-estimator
Or make it simpler, since you know with the current withholdings, you have a balance due approx. $2K per year, you can pay estimated tax payment on your own to cover the shortage.
Form 1040-ES, Estimated Tax for Individuals
https://www.irs.gov/pub/irs-pdf/f1040es.pdf
