Get your taxes done using TurboTax

Thanks

(1) Why would any availability be AFTER an IRS (State of Federal) due date?

(2) Why would the following NOT be supported WHEN TurboTax requires you to add and attach it to your return

AND does the state require filing electronically and not accept hard copies?

I don't understand this, and it hurts my head every time I think about it.

Any takers on some answers?

Thanks in advance

David
