TurboTax has a site showing the available dates of all state products. https://form-status.app.intuit.com/tax-forms-availability/formsavailability?albRedirect=true&product...
I found it by typing State Forms availibility into a box on the main TTax site. https://ttlc.intuit.com/turbotax-support/en-us/
Then choose "When will my individual tax forms be available..." on this page: https://ttlc.intuit.com/turbotax-support/en-us/help-search/?q=State%20Forms%20availibility%20
Then click on the "this tool" link on the 1st line of text on this page: https://ttlc.intuit.com/turbotax-support/en-us/help-article/taxation/irs-forms-availabi[product key ...
