I used TurboTax last year and got direct deposit however I changed banks with a different account number am able to change my account number? Will it give me the option before I file?

Yes it will give you the option, once it gets to your banking information it will ask you if you want to use the banking info from last year, simply click no and it will allow you to input you new info!

Yes, when you go through the steps to file your return you will get to a section where it asks how do you want  your refund, there you can change your bank information.
