You're confusing two different things.
An Identity Protection PIN (IP PIN) is a 6-digit number the IRS provides to taxpayers who were victims of tax-related identity theft. See the TurboTax Help article What's an IP PIN? Do I need one? for more information.
You may be thinking of a five-digit self-select PIN, which can be used to sign your electronic return. You can reuse your Self-Select PIN from last year or create a new one to use. It doesn’t matter which option you choose. See the TurboTax Help article What is the difference between the five-digit Self-Select PIN I created last year and my Self-Select... for more information.
There are separate spots in the TurboTax programming for each of these.
Follow these instructions to enter your IP PIN or to remove one that you accidentally entered.
- Sign in to your TurboTax account
- Open or continue to your return if you don't already have it open
- In the search bar type IP pin (don't forget the space)
- Select the Jump to link in the search results
- On the Identity Protection PIN screen, answer Yes. Select Add and enter your IP PIN in the space provided
- If you need to remove the IP PIN, select the trash icon
- Select Continue, then select Done
