how do i enter cca for class 13 leasehold imp over 10,9,8, and 3 years?

Most leasehold improvements are depreciated as straight-line over a period of 5 years.  Your 10 year old, 9 year old and 8 year old improvements would have been fully depreciated long ago.  There is no purpose in entering them now.  The 3 year old item might best be handled by a T1 adjustment to apply it to the years to the relevant tax years.
