Since you have filed your return, you can print your return plus the worksheets by:
- Log into your return
- You will see the Welcome Home screen (see the first screenshot below)
- Click on Visit My Tax Timeline (Under Download/Print return - you don't want to click on that)
- Under Some Things You Can Do, click on Download all forms and worksheets (see the second screenshot below)
This will give you all of the worksheets that are a part of your return. Look for any that are related to Form W-2.
