After you file

Today I received a notice with a bill for $1260 stating I didn't file an extension. I DID file an extension but Turbo Tax for some stupid reason won't let you E-FILE your 1120S extension as you can with your personal return extension. Another reason to hate TT for business! I filed it March1st as paper filing - the only way you can with TurboTax and IRS is so backed up they have not processed it but have processed my e-filed return. Why won't TurboTax let you E-file your S extension?! If I can't PROVE I mailed it, and they don't process it, I guess I'm screwed! Thanks a lot Turbo Tax.
