@vlaino You will need to contact TurboTax support and they should be able to supply you with the DCN (Document Control Number) for the state return that was e-filed. Then provide that number to the state tax agent or one of their supervisors.
See this TurboTax support FAQ for contacting support - https://ttlc.intuit.com/turbotax-support/en-us/help-article/account-management/turbotax-phone-number...
