Form 4070A is voluntary form used for recording your daily tips and is not filed with your tax return or even submitted to the IRS at all. For this reason, TurboTax does not support this form.
You can print a copy of the form here: Form 4070A
You can also find Form 4070A (Employee's Record), Form 4070 (Employee's report to Employer) and more information in Pub 1244.
To file the form, simply print it off, fill it in, and give it to your employer.
