I haven't received my refund taxes from North Carolina.

Did you e-file your tax return and was it accepted?  
Only the IRS and your State control when and if a Federal or State tax refund is Approved and Issued.

Use this TurboTax website to check the status of an e-filed return and if it was either accepted or rejected - <a rel="nofollow" target="_blank" href="https://turbotax.intuit.com/tax-tools/efile-status-lookup/">https://turbotax.intuit.com/tax-tools/efile-status-lookup/</a>

If accepted by the state use this TurboTax support FAQ to check the state tax refund status - <a rel="nofollow" target="_blank" href="https://ttlc.intuit.com/questions/1899433-how-do-i-track-my-state-refund">https://ttlc.intuit.com/questions/1899433-how-do-i-track-my-state-refund</a>

Due to enhanced identity theft protection measures, some refunds may take longer than normal, which is 8 weeks for electronically filed returns and 12 weeks for paper returns.
