Hi. The IRS withholding estimator directed me to input a dollar amount in line 4(a) and I can not figure out how they got that figure? I also can not figure out exactly what the pension provider will withhold using that figure? (Unfortunately the provider does not know either.🤔). I know the dollar amount I want withheld but have been told if I put that figure in 4(c) there will additional taxes withheld in addition to that they aren’t able to tell me how much. I’m stumped!
