Sometimes, TTX provides some links to some brief instructions.....but the tax software is intended to be done using an interview, and then the software provides the proper calculations.
The main difference between Online & Desktop software is that in Desktop, you can switch to the forms to see what's in them ....but entering $$ directly on the forms can lead to MAJOR software errors, so following the interview is critical.
