I had this same problem with CA state taxes. This worked for me: https://ttlc.intuit.com/community/taxes/discussion/state-tax-is-not-working-on-turbotax-deluxe-2019-...
The problem was that I had old versions (2017 and 2018) installed on the same PC. You have to completely uninstall and reinstall TurboTax, or find the key file that you can just uninstall, to force the download of the latest update. Either that or use a different laptop / computer. Not gonna lie, this is making me re-think whether I want to use TurboTax again next year.
