Without trying to sound evasive, when you used TurboTax in 2020 did you sign up for Audit Defense? If so you should try to retrieve the contact number from the email you would have received acknowledging that and giving them a call. If you did not, there is very little we can do here in Community to assist you. If you used TurboTax Live! in 2020, you can still call up and ask for someone from the Audit Experience team to assist you as they are more knowledgeable in what can and cannot be done. Either way if you used TurboTax Live! you can call and speak to a representative.
The alternative here is to query the questions that have been previously asked in Community about receiving a CP2000 notice. The link is below:
