Form 1040 - Line 15 ) minus LIne 18 is $11 less than LIne 22 All lines in between are blank, . Is there a softrware glitch? or is there a hidden deduction ?

See the 1040 Instructions for line 24 (https://www.irs.gov/pub/irs-pdf/i1040gi.pdf).

Enter any penalty on line 24. Add the penalty to any tax due and enter the total on line 23.
However, if you have an overpay-ment on line 20, subtract the penalty from the amount you would otherwise enter on line 21a or line 22. Lines 21a, 22, and 24 must equal line 20.

So you see that if you have a penalty for underestimated tax paid (line 24), then line 23 will equal line 16 minus line 19 minus line 24.
