Not sure why you did not just do your state returns when you did federal with Jackson Hewitt. As you have discovered, you cannot file "stand alone" state returns using TurboTax. In order to e-file from TT, a federal return must be e-filed and accepted, or you cannot e-file a state return. If you actually prepared a federal return using TT (and it matches what you filed already) then you could try to print and mail just your state returns. You cannot e-file them.
You can try using the state's own tax site(s) and see if you can prepare and file there. Have a copy of your federal return handy to refer to--you will need information from your 2019 Form 1040.
