Can't start my state return in TurboTax 2020 - stuck in a "download and install" loop

Whenever I try to start my Ohio state taxes in TurboTax 2020 Home & Business (Windows CD/download), I get stuck in the following pattern.  I saw this problem happened to some people in TurboTax 2019 and required a TTStateCleanup.exe file to fix it.  Is there such a cleanup program for TurboTax 2020 available yet?

 

Steps to reproduce:

 

1. I go to STATE TAXES tab

2. I click Start button to start state taxes

3. A "Let's Complete Your Purchase Online" window appears

4. I already have the state downloaded, so I click the checkbox next to it and click "Download Now"

5. The state downloads and shows "Your software is up to date."

6. I click Start button to start state taxes, but it just forces me through steps 3-5 again and again.
