Pleasew review what my CPA did on the 1040-x

Hello, I filed a prior return and CPA forgot to include the qbi deduction for my self-employment income. I recently found this out and asked him to file an amended return. Again, the only change should be the qbi deduction. I ran the form through chatgpt and it said line 4b should not be empty (he left it completely empty) and there should also not be two different numbers in line 5 (for example, line 5 column b contains the same number twice, once in parentheses, once without). I'm freaking out because he says it is correct and the deadline is next week. Could someone in the know please comment? Thanks so much in advance!
