It’s GREAT. Typically very powerful. Obviously if you enter in garbage you will get garbage out. Unless your taxes are extremely complicated (and even then) you can typically get it all entered and it will get all the deductions.
Just click on whatever one you want and plug in your numbers. Just plug in this year’s numbers (or even try last years) and see how close it comes. A tip I always recommend is to get ALL your forms from your accountant last year and make sure that you look at all of them and compare them to the TurboTax to see how close it comes.
But it’s really a powerful program and probably will save you a ton of money vs. accountant.
