How do I remove the second job entered on my account?

Click on Federal Taxes tab > Wages and Income > click edit next to the W-2 you want to delete, then click the little trash can next to it. 

The button to the right says "review" instead of edit, then requires an upgrade on the next page. Can I delete this another way?

Click on My Account > Tools > Delete a Form > A list of all forms currently being used for your return will appear. Scroll down the list and locate the W-2 you want to delete. Click delete and confirm the delete.
