The selection to pay SE tax on "both" housing and wages sometimes doesn't stick in Turbotax online. Turbotax claims this user error, I think its a bug.
Most people have been able to resolve the problem by deleting their W-2 and re-entering it. Be sure to check the box for "Religious wages" and enter your housing allowance when asked, even if you already entered it in box 14 of your W-2.
Or, switch to using Turbotax desktop version installed on your own computer from a CD or download, it does not seem to have the same problem, and the download version allows you to make the manual adjustments needed to take full advantage of the expense deduction under the Deason rule.
