You mean they changed the taxable amout of Social Security on 1040 line 6b from 0 to an amount?
For the Social Security, you get 0 on 6b if you didn't answer the Foreign question right. Or if the amount on 6b is too low and you are married you answered it wrong for one spouse.
Starting in 2024 there is a new question asking if you lived in a foreign country. People were answering it wrong or skipping it. Go back through the Social Security entries and check, check for each spouse if married. If the IRS adjusted your return you do not need to amend.
Check the top of the Turbo Tax Social Security Worksheet. There is a box to check if you lived in a foreign country.
