Yes, you entered your infomration correctly. When you begin an amended return, the software resets the refund meter to $0. If you have completed all of your changes and the meter remains at $0, the updates you made to the return did not affect on your refund amount.
Please be advised: If entering your 1098-E did not affect your return, you do not need to file an amended return. For more information on how the information on your 1098-E affects your taxable income, please see the link below.
