Required Minimum Distribution

RMD for 2019 was not totally distributed in 2019 because of a Notary error. The final portion was distributed on January 2, 2020 and I received a 1099-R in that year.  In 2019, TurboTax prepared a form 5329 for me and included my Waiver explanation statement.  I have heard nothing from the IRS about it.  Since this distribution was an RMD, although not for 2020, do I need to somehow include an explanation with the 2020 return that this distribution applies to 2019 RMD requirement?  TurboTax is not preparing a form 5329 for me this year.
