Turbotax entry for my 1040 line 5a doesn't match what I entered from my 1099-R

This question is from my 2022 return. My 1040 line 5a value not represent what is on my 1099-R line 1 as the 1040 instructions indicate it's supposed to. It's not a problem as the taxable amount on 5b is correct. My 1099-R has the same values for box 1 & 2a. (1-Gross distribution & 2-Taxable amount). What is on my 1040 line 5a is more. I understand that what ends up on line 5a on the 1040 form comes from the 1099-R worksheet which I've also looked at. The higher number is on line 22( & 25) of the 1099-R worksheet under Pensions and Annuities section. Where does this number come from? I used the downloaded Turbotax 2022. It's not a problem for me as the taxable part is correct. Thanks.
