There are several IRS forms which have 'hard' numbers pre-printed on the form. I think that is all that you are seeing in Part II line 14 of the IRS Form 1040 Schedule SE Self-Employment Tax.
Please check that the correct amount transferred to the 1040. The amount on line 12 of Schedule SE should have been transferred to Schedule 2, line 24. Schedule SE, line 13 should have been transferred to Schedule 1, line 15.
If that's the case, the correct computation was made and is reflected on Form 1040.
Please see the thread from a previous post about this topic here.
