RMD is the Required Minimum Distribution you are required to take from your 401k or similar retirement plan once you attain age 70 1/2 in a tax year. It is based on the balance in the plan at the end of the prior year. TTax should have covered this for you if you used the step-by-step method of input. if you attained 70 1/2 in 2018 you need the value of your plan as of Dec 31 2017 to compute the RMD. usually this is provided by the plan trustee. the percentage for the first year is between 2-3%. you must then take the distribution by April 2019 if you did not take it in 2018.
