While the 3115 is included with the program, there is practically no help or guidance provided for it. The possible uses of this form for "fixing" things is just to complex. Why TTX included it is beyond me. But for those who know what they're doing when it comes to the 3115, I guess it would benefit the company to not lose the customer.
Overall, the 3115 is not simple by any stretch, and if you don't know what you're doing when it comes to the 3115, you are highly advised to seek professional help. The math is "never" as simple as we may think. Doing the 3115 incorrectly to fix a problem, can actually be the catalyst that triggers an audit and end up costing more on the tax front in the long run.
