Don't know why Intuit hasn't fixed this yet, but this was my workaround...
After importing my 2023 TurboTax return into 2024, there was no way to update SSA-1099 - clicking update just brought you back to the same place. I went into the Forms view and selected Social Sec and double-clicked on each of the yellow (user entry fields) in the Social Security Benefits Worksheet and deleted any of the supporting details that were carried over from 2023. I also noticed that the Railroad Retirement benefits button at the top of the form was checked when the worksheet first opened; be sure to uncheck this if it doesn't apply to you! I then went back to the Step-by-Step view and clicked the update button and the walk through worked as it should have the first time!
