proof of child support for stepchild needed ?

[quantumgirl 0]

The document checklist says:

If you have a dependent spouse or child(ren) who do not live with you, send:

Any court or government order to provide financial support; and Evidence of your financial support (including evidence that you have complied with any court or government order), such as:

a.Cancelled checks;

b.Money and receipts;

c.A court or agency printout of child support payments;

d.Evidence of wage garnishments;

e.A letter from the parent or guardian who cares for your child(ren).

Does this pertain only to MY biological children or would it include my husbands chid from a previous marriage, who I listed as my stepchild in part 10?
