Deductions & credits

I'm a retired Federal Employee and contribute to CFC also.  I enter all of mine as Combined Federal Campaign, PO Box 99, Haymarket, VA 20168.  Just a word of caution, do not depend on the contribution statement that is listed in the CFC website.  Take the actual deductions from your payroll statement or OPM annuity statement (year-to-date) for the entire year.
