Form 8606 - Line 6

We're married and file a married joint tax return. Last year, my husband rollover $5K from his Traditional IRA to his Roth IRA account at Navy Federal. We received 1099 R from Navy Federal.  I have a rollover Traditional IRA at Vanguard from previous company. Line 6 of form 8606 - "Enter the value of  all your traditional, SEP and SIMPLE IRA". Do I enter the value of my husband's traditional IRA account at Navy Federal only or do I need to add the value of my traditional IRA account at Vanguard also even though we only rollover at Navy Federal account? Thanks.
