I have used HRBlock for several years, now using Deluxe though I used the premium in the past when spouse was self employed. Results seem to be good. No contact from IRS, generally. Embedded Help is useful, but not always specific to my situation. The included call support helps bridge that gap. Primary irritation is the updates that trickle in deep into the tax preparation cycle. It is not obvious if the (pending) update will impact my return. In some cases, I have the "interview not complete, update pending" message in areas which could impact my return. If I owe money, I am OK waiting closer to 15 April, so this is a minor problem. If I will receive a refund, I have to decide whether to proceed at risk, or await the updated interview software. There is typically no ECD provided by HRBlock for the update, though April 15 is a drop dead date, I suppose.
completed the 2023 1040 return and submitted it on March 7 have heard nothing since from IRS IRS says return accepted but nothing more as of writing this comment 6-14-23
Don’t like that format changes every year. Do like that it brings personal information forward so you don’t have to re-enter. When you don’t quite understand something you can easily find the answer.
