Items are carefully listed on the 4562 when it is placed in service. Then it just gets lumped together into line 17 after that. You should have a form 4562 each year that any items are being depreciated. You may have worksheets as well. When you view your return, mark that you want to see all the worksheets, not just the forms.

For information from when the item was placed in service, you generally need to look at the Form 4562 for that year. Remember, you must save all tax returns from purchase until sold plus 3 years minimum.
