@Williamt13555 You might try using the free TaxCaster tool instead of the estimated payment calculation interview. Regarding calculating your RMD, your plan administrator should be able to provide the information you need. The IRS has Required Minimum Distribution Worksheets, too, or you could search for an RMD calculator online, but you'll need some details about your retirement plan to get started. It's standard for the plan administrator to withhold 10% from an RMD unless the recipient indicates otherwise. (I'm not sure this fully addresses your RMD concerns but I hope it helps,)
