Timing of Submitting My Fed & State Tax Returns

I completed my Fed and State tax returns on Saturday, March 13. I then signed out of TurboTax.

I want TurboTax to submit my completed Fed and State tax returns on April 9th.

How can I make that arrangement with TurboTax? Please give me

an email address to which I can send my specific request to TurboTax.

Please reply by this coming Tuesday March 16.

Thank you.

Henry (Hank) Steinman
