Typically, all of the above information would be on the 4562's for that property. I'm somewhat surprised you don't have those documents included in your printout of your 2021 tax return. I would highly suggest you contact the CPA and ask for that, as you "did" pay them for it. The CPA is morally obligated to provide you a total and complete printout of all documentation, as you would need that if you were audited so you can "Follow the numbers" and see how specific figures and numbers were calculated and arrived at.
Do you have any document that shows the in service date for each individual asset, along with the cost of that asset?
Do you have any document that indicates you took either SEC179 or the Special Depreciation Allowance on any asset, along with the amount taken, and the original cost of that asset and the date that asset was placed in service?
If you have that information, then you have all you need.
Take note that I would not expect you to have anything for a SEC179 deduction (but you could), and it's very possible that you could have something showing a Special Depreciation Allowance on a given asset.
