How do I see the detailed calculation of unrecaptured section 1250 gain?

I am filling out Form1065 in TurboTax Business 2021 Desktop. It calculated a section 1250 gain on Line 9c of Schedule K, Form1065, Page 4 because I sold depreciated rental property.

I would like to see the details of that calculation, but I can't find it.  Right-clicking and going to Data Source says it comes from Form 4797, but that only gives me the amount on line 10. 

Any ideas?
