Form 4562 line 26

I bought a new truck the end of 2024. Took a 179 deduction and will depreciate balance. TT fills in the 4562 but  leaves line 26 blank. According to the IRS this needs to be filled out for a "first time" asset placed into service. I decided to manually fill it out and it changes parts of the 4562.  Don't understand why TT won't fill it out and not sure what to do.
