The IND 181-01 reject code in TurboTax indicates that there is an error with the taxpayer's Identity Protection Personal Identification Number (IP PIN). To fix this issue, you should take the following steps:

1. Verify your IP PIN: Double-check that you have entered your IP PIN correctly on your tax return. Make sure that you have not transposed any of the numbers or made any other errors when entering your IP PIN.

2. Request a new IP PIN: If you have verified that you entered your IP PIN correctly and are still receiving the IND-181-01 reject code, it may be because your IP PIN has changed. You can request a new IP PIN from the IRS website at https://www.irs.gov/identity-theft-fraud-scams/retrieve-your-ip-pin. Once you have your new IP PIN, enter it on your tax return.

3. Contact the IRS: If you have tried the above steps and are still receiving the IND-181-01 reject code, you may need to contact the IRS directly for assistance. The IRS can provide guidance on how to resolve the issue and may be able to assist you with obtaining a new IP PIN.

4. Resubmit your tax return: Once you have fixed the issue with your IP PIN, you can resubmit your tax return to the IRS using TurboTax. Be sure to review your tax return carefully for any other errors or issues before resubmitting it.
