Can I claim the Foreign Housing Exclusion but NOT Foreign Income Exclusion? I contributed to a Roth IRA so I can't exclude my foreign income, as it's my only income.

Turbotax seems to only allow me to answer questions about Housing Exclusion if I'm also applying for the Foreign Income Exclusion. I understand I can't contribute to a Roth IRA if I don't have taxable income, so I can't claim the Foreign Income Exclusion. However, I'd like to claim the Foreign Housing Exclusion if possible.
