Line 14 adds lines 12c ( AGI less charitable contributions) to 13 (QBI) as opposed to correctly subtracting 13 from 12c. to obtain the correct value for line 14. Line 13 specifically says QBI "deduction", any rational person would subtract line 13 from 12C to obtain the benefit of QBI instead of adding it and not only losing the QBI deduction but paying tax on it. But TT is not rational. Whomever is writing their software needs to be fired. I love the TT advertisement, "taxes done correctly, guaranteed". I am uncertain if that answers your question of "how do I see line 12c"?
The tax code requires that the QBI be entered on Line 13. Then it requires that Line 13 be added to Line 12c with the result being on Line 14. Then it requires that Line 14 be subtracted from Line 11 with the result on Line 15 as the Taxable income.
