How to enter 50% of annual depreciation expense to Sch E

My partner and I have had two single family rentals for the past 12 years.  We split expenses and revenue 50/50.  Turbo computed the split and posted 50% of the expenses and revenues to Sch E for each of our returns.  There was one exception, Depreciation was calculated by Turbo and posted to Sch E at 100 % for both my return and my partner's.  I just noticed this now.  Why didn't Turbo catch this?  It did the calculations and knew the percentages didn't match.
