Results got rejected by IRS multiple times. Help was nonexistent. Basically said change what’s wrong and resubmit! Had to keep guessing what could possibly be wrong and resubmit. I have a simple return and nothing has really changed much from previous years. Never had this issue before.
Pretty easy to use if you know basic tax preparation rules. I would like more popup help that provides a one sentence explanation of the long lists of credits, adjustments, etc., so users could see if any of them apply to them.
