IRA Distributions - nontaxable

I am at the program point. Here’s a Picture of Your 2024 Income
Turbo tax 2024 Deluxe program Federal Taxes comparison chart 2023 to 2024 is showing thousands of dollars “IRA Distribution - nontaxable” for 2023 & $0 for 2024.  I do not have any IRA nontaxable accounts RMAs for any year. Turbo tax also shows IRA Distribution - taxable amounts for both 2023 & 2024 & do have taxable RMAs for those years.  The 2023 Total Income also shows Thousands more dollars income than the 2024 column total.  2024 should be a better year.  When I look back at my 2023 tax turbo tax forms I don’t see any nontaxable IRA records.
   Where are these numbers coming from?  Thanks in advance😀
