Even more frustrating because it doesn't tell you that you haven't done the calculation or worse, you haven't transferred a field from one form to another.

I failed to copy my self-employment tax back to my 1040 for 2020, despite having calculated it correctly. No warnings, the form filing went smoothly, and 4 months later I got a notice from the IRS.

It's insanity.

I hear you. I keep hoping they will add more calculations in future versions, and they do, little by little.

My suspicion is that it is deliberately deprecated due to pressure from for-profit tax prep companies.
