Is it possible to file the NC state tax return jointly with my spouse while I'm waiting for the ITIN number?

If you filed your federal return with an ITIN application, you will need to wait for the ITIN before you can send your state return. Once you receive the letter with the ITIN confirmation, you can then mail your NC return with a copy of the assigned ITIN.

What if I don't receive the letter with the ITIN confirmation before April 15, 2025?

File for an extension for North Carolina.  You can do this in TurboTax or go to File an Individual Income Extension - NCDOR. @rahulkuttikol
