How do I view the full depreciation schedule for a 2018 tax return?

Try printing from the Print Center
Log back in your TurboTax account and "add a state" to open the return back up (you are not really adding a state, just to open it back up), then
Click on Tax Tools on the left side of the online program screen. 
Then click on Print Center. 
Then click on Print, save or preview this year's return.  Choose the option Include government and TurboTax worksheets

Thank you - I forget how to do this every year and Turbo Tax customer service couldn't even help me with it.  Thankfully a kind soul like you described exactly how.  Thank you

Hi,

I am trying to get a copy of my 2019 Depreciation and Amortization Report -Worksheet. I am not able to "add state" since I cannot see that option in TT online like before. Is there something new in the program that not allow doing this?

Please let me know.

You can see the Depreciation and Amortization worksheet when you click on the PRINT CENTER.  Here are the steps:

1. Sign into your 2019 tax return.
2. Scroll down and then click Add a state.  
3. Click Tax Tools 
4. Click  Print Center
5. Click  Print, save or preview this year's return.  
6. Choose the option Include government and TurboTax worksheets

The ADD A STATE trick only works for the current year return (and only until the season ends in October) ... for all prior year returns all that needs to be done is to save a PDF of the return from the tax year ... it will have all of the worksheets included with the return.

To access your current or prior year online tax returns sign onto the TurboTax website with the userID you used to create the account - https://myturbotax.intuit.com/

Scroll down to the bottom of the screen and on the section Your tax returns & documents click on Show.  Click on the Year and Click on Download/print return (PDF)
