Retirement tax questions

Sorry, I must have not been clear. I'm talking about the current RMD due to be reported on my 2019 tax form which I have not yet filed. This RMD is based on the balance in my IRA on 12/31/19. 

Under the new rules in the Trump bill, should I now cancel the RMD entries on my 1040? 

If so, do the RMD funds have to be sent back to the custodian or are they just considered a tax free withdrawal from the IRA?

Thanks,

Jerry
