My 1040 box 11 for my Spouse and I is being rejected. How do I fix this?

I filled jointly with my spouse, and Box 11 on our 1040 shows a 27K AGI. I have my 1040 in front of me and it shows that 27K. I'm being asked for my Spouses AGI, but we are filling jointly and she had no income. What should I put to not be rejected?
