I would not recommend break them out. Enter your 1099R as you received. If you are over 70 1/2, you will see the RMD screens after the 1099R entry screens, Enter "None of this withdrawal was RMD". On the next screen you will be asked what you did with the money. You can indicate on the following screens that you rolled over the $19,000. There is no RMD requirement for 2020. That should take care of the roll back into the Traditional.
I am a little surprised you did not get a separate 1099R for the roll from the traditional IRA to the Roth IRA. It sounds like this was a separate transaction and a separate 1099R should have been gnerated.
