I am in the same boat and I feel too embarrassed to give them a form with "Do Not File" on it.  To make matters worse, the S-Corp and other business returns are the same way!  I can't get anything finalized and apparently Lacerte expects us to somehow finalize them all after 2/27.  I am going ahead and e-filing the federal for clients with refunds.  They will get their refunds before I can even print a tax return!
