I have the potential to some expenses two different ways, How can I prepare my filing; save it, and then run a second scenario to see which is more favorable, without losing the original filing?
You have the ability to do multiple returns in the desktop software. It's the same as if you were doing a return for yourself and one for a relative. You can use different names to identify them. When you exit a return, you are asked if you wish to save it. Answer yes.
