Well, I am not hampered by any kind of expertise here, but I will guess that to get a $5K refund, your total payments have to be $5K over the actual tax due. So you will have to figure that or just grab a number big enough that you're sure you've overpaid by the $5K. Withholding is considered to have been paid during the whole year, not in December, so that may help you if you underpaid first quarter, but this SGOTI really knows nothing factual about the situation.
Re quarterly payments, when I was doing them I just paid what my tax guy told me to pay. My guess is that they totaled the safe harbor amount but he is retired so I won't bother him for the answer. My life has simplified since that era so now I just do my own taxes and the December withholding thing. I have never mixed that with quarterly payments.
To get down to the basics, if you pay estimated tax, the IRS calculates how much you should have paid at each waypoint (4/15, 7/15, 10/15 and 1/15) based on your earnings in each of those quarters. If you withhold, however, whether through regular withholding from a job or withholding from an IRA distribution, it is considered to have been withheld evenly throughout the year. So you will avoid under-withholding penalties, so long as you come within $1000 of your ultimate tax bill or pay 110% more than last year's bill, even if that withholding was done solely in connection with a December IRA distribution.
