I had same experience. TurboTax tech support laid a goose egg and left me high and dry.
I tried every solution (reinstall, shut off firewall and antivirus, cleared browsing history...hours wasted.
I found the solution on a websearch....do into control panel, click uninstall a program. Then click on the last version of Microsoft Visual C ++ 2015-2022 Redistributable (x64) and click "Repair."
Program immediately worked. No thanks to tech support.
