I had already advanced through the return such that my converted rental info was deleted.
At this point, you have no choice but to clear the return and start over from scratch. The only time you can import from the prior year tax file, is when you first start the return. That's it.
You did not indicate if you are using the online version of CD version of the program. If using the online version and you've already paid for it, then you can't clear the return and start over at all. You get to re-enter the history the long way - one keystroke at a time. You'll need both 4562's and the 8582 from the 2019 return to do that.
If using the CD version, simply delete the .tax2020 file in the documents/turbotax directory. Then when you fire up the program it's "as if" you're starting for the very first time after installing it.
