It depends on what Forms are included in your IOWA. For example, the Iowa Composite return is not available until February 23rd. Some forms are not supported by TurboTax so you may need to efile your Federal and mail your State return.
You can also efile your Federal now and return to TurboTax to file your State when the forms are available.
