Foreign Earned Income Qualifies for Exclusion but Still Increases Taxes

My spouse earned income of $22,715 from a Canadian employer; he meets the physical presence test in Canada and Turbo Tax reports that the income qualifies for being excluded after I complete the Foreign Earned Income Exclusion interview. Form 1040 shows it being excluded on line 8 (Other income from Schedule 1), line 10, however, with it entered into Turbo Tax, and no other changes made elsewhere in the return, Turbo Tax reports on line 16 of the 1040 (Tax), increased taxes of $2,289.

 

I've gone through the interview many times now and keep getting the same result. Do I need to enter data somewhere else in Turbo Tax?

 

Whatever clarity anyone can provide would be much appreciated.
