what does 4D really mean on my 1009R? Can I just enter the info on it? It's not my RMD it's my dad's who died, can I ignore the RMD questions?

Code 4 is used to report that the retirement proceeds are from a death.  Code D indicates that the payment is from an annuity from a nonqualified annuity. Only the earnings from these distributions are taxable as the annuity is funded with after-tax dollars.

As long as you enter the information from your 1099-R as provided, you should not be prompted to answer any questions regarding a RMD.  I recommend following the steps in this link to get to the 1099-R input section. Select Update to the right of IRA, 401(k), Pension Plan Withdrawals (1099-R) on the applicable 1099-R.  

On the screen asking you to enter the 1099-R, be sure to enter the applicable codes under Box 7.  There are two boxes where you can enter both of your code options as listed on your 1099-R form.
