Since the Retirement Income section is not yet available how can I best estimate how a non qualified annuity withdrawal will affect my taxes?

I returned my RMDs this yesr so have no retitrment income from that surce this year. However I already had some taxes withheld so I presume I will get a 1099-R for that. Also I have been withdrawing gains from a non-qualified annuity instead which I assume will mean another 1099-R. I want to figure out how much additional money I can withdraw from this account without having a serious impact on my taxes. Right now I'm including my esitmate for that under Interest but that forces me into a requirement for Deluxe which I don't think I'm really going to need this year. Is there a better way to esitmate say by reporting that income under Other Income?
