line 11a is the total of standard or itemized deductions + the deduction for qualified business income. it is not a tax
taxable income is on line 11b
first tax line is 12a
12b includes amount on 12a + the taxes on schedule 2 and 3
13a is child care and dependent credits
13b is 13a + line 7 from schedule 3
12b less 13b = line 14
14 + 15 = line 16 total tax
