<prompt> Human: How do I get my 900 back?-I filed too quickly with TurboTax and everything went through. -Turns out I missed a form regarding an HSA account forgot the form , so I amended it in TurboTax and I now have to pay 900 less but already got billed for the original amount.-Says my Federal eFile is ready to mail. Im guessing amendments can only be mailed...-Do I just mail-in these forms I printed? Why is america so complicated??Thanks PF!  <response>: Youll file the amended return and theyll send you a check or direct deposit for the 900 you overpaid, just like if you had overwithheld throughout the year.
