@DoninGA left a great suggestion to change your MD e-file to mail or I'm not ready, that way you can still efile your Fed return, when the IRS accepts the federal return you can then come back to TurboTax and change the state filing method back to e-file and see if the form is available then.
Hope this helps you because it definitely helped me as I just did it and have filed my Fed taxes just now.
