Deductions & credits

Pertaining to the community advise I'm requesting a response to one additional question:  How do I show a csot basis as one asset/property when using Turbo tax it  specificially wants  identified the "original  purchase price" and purchase date of the rental properlty, which would be my $45K.  Then the program states specifically that any improvements should be added as an "added Asset".  I understand the $45K will be fully depreciated, but Turbo tax has not made allowance to record the $45,000 - $27,000 + $255,000 as one asset/property at the "original price".  Have I missed something?
