Is the 529 limit of $10,000 (for married filing joint) per household or per child account?

TurboTax is telling me that I cannot enter more than $10,000 on Part 1 line 1 of the 529 section.  But I have friends that say the $10,000 limit is per child.  (Although they are in NJ and I am in NY).  Could someone confirm if the limit is per household or per child?  And is there a difference between NY and NJ?

Turbo Tax is correct. The contributions to a New York 529 plan are up to $5,000 per year by an individual, and up to $10,000 per year by a married couple filing jointly.

NJ does not have a contribution deduction to 529 plans; therefore, residents can keep making contributions until the plan value for a beneficiary is $305,000.
