Deductions & credits

@jtax if you have not completely lost patience with me I have now accessed the printed preview and can say that Schedule 1 Foreign earned income exclusion from Form 2555 . . . . . . . 8d amount is 96,893 - which is all of our joint FEI.

And to match the screenshots you shared previously, here are

Form 2555 p. 3:

and Schedule SE:

Compared to your hypothetical I seem to be paying self-employment tax on a Net profit or (loss) [from Schedule C, line 31] that is much lower than the combined self-employed US earned and Foreign earned income I am reporting. If the total due of $3,800 (Sch. SE line 12) seems right then my problem is solved. But a basic calculation of Form 2555 line 45:  64,745*12.4% =   8028.38 tells me I may be missing something. 

You are very kind to have stuck with me thus far. Any further help is a tremendous act of altruism!!!
