If I remember correctly, you need to manually do it (the bottom of page 2 on the "Enterable 4797"), but I'm not 100% sure of that.

Test it out and see if the program automatically fills out the bottom of page 2 of 4797.  If it doesn't, you need to manually do it.

As a side note, you may want to double check that you elected OUT of Bonus for the vehicle in 2019.
