After you file

To make it clear and not confusing or annoying.

 

I just found out you can download the TurboTax Debit app called Turbo by GreenDot

 

Once you download it 

 

Sign in

 

Then it will log you in

 

Once you are logged in,

 

Hit the left hand corner with three bars.

 

Go to settings

 

Then you will see you can change your pin

 

Hope that helps.
