Does the new Roku Ultra 2020 support connecting a Bluetooth keyboard?
No, sorry but it does not.

Discovered I could run the Roku app on my Galaxy s10e. Then paired my logitech K380 bluetooth keyboard to my phone & I can use physical keyboard to enter into the Roku app which puts it into my TCL series 3 Roku TV for searches etc.. this workaround might work for you.
Thank you for this bit of workaround knowledge. You rock bro!
