@wideglidejrp TurboTax doesn't fill out Form 8453 until you are in the filing process. Until then, it doesn't know if you are going to file electronically or by mail. Form 8483 is only used if you e-file, not if you file by mail. When you start to file, and you select e-file, TurboTax will fill out the form and allow you to print it.
