It doesn't matter how the AI came up with its wrong answer.
No correction to the software is needed. Including the German Social Security amount in box 5 of Form SSA-1099 has been the common practice in TurboTax and other tax software for many years.
If you are using the desktop TurboTax software, you can use Supporting Details in box 5 to enter the U.S. and German amounts separately if you prefer to do that. Box 5 will then show the sum of the two entries. I don't think Supporting Details is available in TurboTax Online.
