I'll provide clarification. in online or desktop direct entry in the forms will invalidate TT guarantee. As a matter of fact that the app may even prevent you from e-filing due to direct entry. In the desktop app there's step -by-step mode much like online. there is also forms mode which allows you to make entries in worksheets that carry the info into the actual forms. this is not a violation. I have always used desktop and forms mode. And yes you can e-file.
