Line 15 has positive taxable income. Line 16 says tax "$0" How do I override to correct?

[DTLNYC]

On Line 15 Form 1040 it says I have $34,137 in taxable income but on Line 16 Tax it says $0. This is clearly incorrect. IRS Tax table calculates at $3618. "Override" is greyed out, so how do I override "Override"? No, I don't have any tax credits, or other offsets. And it does say there is S-E tax due which IS correct (but that's it). Is this a bug which an update should fix soon?  I am FULLY up to date

On your tax return did you enter any Qualified Dividends or Capital Gains?  If so, the IRS tax tables are not used.  What is used is the Qualified Dividends and Capital Gain Worksheet as shown on the Form 1040 Instructions page 38 - https://www.irs.gov/pub/irs-pdf/i1040gi.pdf#page=38
