No new corrected 1099R needed.  If indicated the withdraw was due to Covid, you should have seen some screens if the entire distribution was all due to Covid or only partially.  You can also look at the 1099R in Forms view by selecting forms in the upper right hand corner of the screen.  Scroll down the forms then select the 1099R.  Scroll down the 1099R and you will see the selections for the Covid deferral.
