Form 5227 is not filed as part of the 1041 income tax return.
Form 5227 is for financial reporting and is filed separately from the Form 1041.
See the instructions at http://www.irs.gov/instructions/i5227/ch01.html#d0e277
U.S. Address. If you are located in the United States, file Form 5227 at the following address:

This is similar to the individual that reports income on a 1040 and also separately reports foreign accounts and amounts held in those accounts.
The 1041 is reporting income subject to tax. The 5227 is reporting other information such as the balance sheet.
Please ask if you need clarification.
