Get your taxes done using TurboTax

TurboTax 2021 Deluxe, at least, does provide the "Modified Adjusted Gross Income Worksheet". I don't know about other versions.

 

To find the worksheet, go to the Forms view and click Open Form. Set the return type to  Form 1040: Individual and then search for "modified". "Modified AGI Worksheet" should be the one and only page that's found. Click Open.

 

If you want to print the form, display the worksheet (as above) and then Print Active Form (under File in the menubar).
