Taxable amount for line 5b in Federal 1040 for 2024

TurboTax desktop is not correctly calculating the taxable amount in line 5b of the Federal 1040.  I have checked all of my 1099-R forms and come up with a different amount for line 5b.  My calculation for line 5b is $176,852.35.  TurboTax comes up with $156,377.

 

Can anyone come up with an explanation?  Has anyone else experienced this?
