I can't find a place on turbotax to electronically file for a tax exemption. All I get is a place to print Form 4868.Has anyone else had this problem?

A tax exemption?  Or a tax extension?
If an exemption, you need to explain in detail why you think you are exempt from paying taxes.

Sorry I meant an extention

Go to this TurboTax website to electronically file an extension request - https://turbotax.intuit.com/irs-tax-extensions/
