e-file preview - issue with what is generated

[Curious One]

i tried to file electronically but wanted to preview in advance. when doing so i expected to see only the necessary forms for filing, but instead got many more pages, including calculations.  this calls into question what will actually be included with the e-filing itself when i hit the button.  i tried to change the setting to official forms only, but that generated an error message so my confidence wasn't increased by that.

You can rest assured that the only forms that will be efiled to the IRS are the forms that are required to be included in your tax returns. None of the worksheets or other forms in your file that should not be filed are coded to be accepted by the IRS.
