@embrewer , sorry I could not get back to you earlier--please excuse.
(a) from your answers , I think I better understand your situation and therefore venture to say that you should be able to prepare the return by yourself;
(b) the problems that you are seeing ---- housing exclusion vs. housing deduction -- is essentially the same . In case of housing exclusion the assumption is that your employer is providing you help ( monetary ) in paying for "equivalent" housing in a foreign location and therefore is eligible for exclusion just like foreign earned income. For Self-Employed you are both employer and employee ( kind of ) and so a commensurate amount should be eligible for exclusion along with your foreign self-employment earnings. TurboTax just may not be making the distinction.
(c) the issue of asserting SECA ( equivalent of FICA for the self-employment but with a bigger bite ) exemption based on totalization agreement should work -- thought there is a screen to do that. However, I may be wrong.
Therefore , I seek a little more time -- perhaps this time tomorrow ( 9:00PM PDT -- UK -8 hrs ) -- to recreate the scenario and see if and why TurboTax is misbehaving. Please can you wait that long ?
Stay safe
