Great program, but, I had one glitch. The W2 employer ID must have a - after the first two digits. This was not how it was listed on the W2 form and when I keyed it in the way it was on the W2, all of the digits were not posted resulting in a Reject from the IRS.
It does the job but there's nothing special or especially intuitive about it. When it has you going back to add and subtract lines from previous returns it has access to, it makes you wonder why you bought the software.
