Is There a CPA in the House?

I have a minor change to make to my IRA withdrawal tax withholding to avoid surprises like this year.  If so, please contact me.  I suspect it will take you 2 minutes to do.  My algebra is too rusty. 

One of you wonderful readers directed me to a CPA who recently went through firearms training.  She told me enough to see what I should have seen on my own.
