i guessing but since you used the term RMD i assume you turn 70 1/2 in 2018. if so the 2018 RMD was required by 4/1/2019.
you took part in 2018 and the rest before 4/1/19 so you're ok
before 12/31/2019, you must take the full RMD for this year. the trustee should inform you of the amount. if not contact them. do not wait til the last minute, processing delays could result in it being made early in 2020 which will cause problems.
