Spousal contribution to SEP IRA

I have earned income from self-employment, and my spouse does not work. We file jointly.

 

Can I contribute to a SEP IRA for both myself and my spouse?


In TurboTax, clicking 'maximize contributions' for both of us puts me at the $66k limit, and her at $0. Is this correct, or given enough earned income, can I contribute $66k to my spouse's SEP IRA as well, totaling $132k?
