State Tax Return after ITIN

[steofn3]

I am a resident alien for tax purposes. My wife arrived in USA in 2019 and we filed jointly 2019 taxes along with her Form W-7 (ITIN application). We mailed our tax return + W7 form. She just now received the ITIN  on Nov 16, 2020 -- way beyond the official deadline of tax filing. I know that the IRS will now go ahead and process our 2019 tax return -- which might take additional 1-2 months.  

Since I have SSN and my wife got ITIN just now, my questions:

1. Should we wait for IRS to process our federal tax return before we file our Indiana State tax return? 
2. In case we can just go ahead with Indiana State tax return without waiting for federal, how do we do it? I know I should go to TurboTax, enter my wife's ITIN and then electronically file State tax return. Is this correct? 
3. Since we filed physical tax return for federal, can we file State tax return electronically?

E-filing is closed permanently for 2019 returns.  Your state return cannot be e-filed.  You need to print it, sign it in ink and mail it to the state.

Ok, thanks! Regarding my first question: do I need to wait for the federal return or I can go ahead with the State return?

Go ahead with the state now... no need to wait on the federal.
