E-file rejection IND-525 happens when the date of birth for the first person listed on the return is either incorrect or doesn't match IRS records.
First, get a copy of your 2023 Form 1040 and find the first person listed. (You'll be the only one listed if you filed by yourself.) Then, find an official document like a birth certificate, passport, or driver's license, to ensure you have the correct date.
Select your version of TurboTax for instructions and be sure to enter the date in the standard U.S. format of MM/DD/YYYY.
