I don't understand your question . If no distribution, then why would you get a 1099-R?
If no distribution was required in 2020 and you did not take one, then no 1099-R would have been issued.
You may be seeing a blank Form 1099-R that transferred in from your 2019 tax file. If so, and it is creating a review error, delete it. See: How do I delete forms in TurboTax Online?
