1) My tax lawyer agrees depreciation expense needs to be prorated
2) TT's tier-2 support agrees the software has a defect and it should prorate it.
Reading your screenshot this harkens back to previous versions of the software where (a) you could override the non-prorating of depreciation and (b) e-file. In TT-2018 if you override to take the appropriate prorated depreciation, you cannot e-file. This is the aspect you appear to have not noticed in my original post.
