Why I'm not permitted to contribute more than the amount of my income (zero last year) to my IRA, if I'm married, filing joint tax, spouse had enough income with no IRA?

I made only $800 contribution to my Traditional IRA and my Spouse did 0 contribuition last year since she has 401K. Our combined AGI (joint) is ~68k. It seems Turbo Tax has a glitch on this.
