@5bsagreen Sorry, This is a common misunderstanding. If you are both over 65 and in the phaseout amount, the 6% reduction is subtracted from EACH spouse's 6,000 effectively making it 12%.
It is phased out for EACH spouse. Fill out Sch 1-A yourself and see. It's pretty easy. Then why would they even have 2 lines 36a and 36b for spouse on Schedule 1-A?
IRS Schedule 1-A
