"on my version"

Of which program? I asked the question, if you are using ProSeries?

And I gave the Reference link to the Source = the IRS interactive wizard.

"In other words is their gross income $3900 or $6900? They qualify in every other way."

TaxGuyBill addressed this part:

"1) "Income" does not count for the Support Test. Money SPENT counts for the support test. That could be from anywhere, including earned income, unearned income, gifts or savings."

Unemployment is income, but it is considered Unearned and is treated the same as investment income. The question you asked is a bit of a mix of Gross and Dependency, which don't really relate to answer your question.

There already is a lot of this type of detail in this topic. I would reread it to see which parts apply to what you are asking, because the title has to do with Kiddie tax, and you specifically don't want the "child" parts, apparently. That's another reason I linked to the IRS for you to use their resources.

You should now have everything you need to answer your own question. If you cannot make the software give you the result you determine, that would be why you ask this community of peer ProSeries users.
