I can’t find the tool button

When using the Online software....it doesn't show until you re inside of your actual 2019 tax file.  IF you are on the main Home page, it doesn't show.

One you get into your 2019 tax file, it will be in the left-side menu

hit <Tax Tools,,,, and then <<Tools

Do you have a Mac?

Click on forms on the upper left side once you are in your Turbo Tax return. 
Scroll down to the form you want to delete. 
Once is highlighted blue, click your delete key on your keyboard. 
click “remove” to the question. 
To go back to your tax return, simply click the same upper left tab “Easy Step“. 
If this helped you please give it a thumbs up. Good luck.
