If
your mortgage lender is foreign, but the interest is otherwise (legally)
deductible, then in order to get around any blockage such as this in
the TurboTax software, you can simply substitute a US address (such as
your own, for example) and a "fictitious" EIN (Employer Identification
Number) or SSN into the relevant data entry fields in the program. For
instance, 1234 Main Street, Anytown, USA, EIN # 93-1234567.
That will
allow you to move beyond any data entry error screen issues. Moreover,
none of this mortgage lender information will be transmitted to the IRS,
other than the amount, so it's really not too important what you input
here.
Of course, please do save your actual foreign mortgage interest
payment records, so that you'll be able to produce them for the
government authorities, in the unlikely event of an IRS audit or
examination.
Thank you for asking this question.
