TX is a community property state. But if your sister's spouse owes child support the IRS can seize their entire federal refund unless she files an injured spouse form or files married filing separately---both of which are trickier to do in a community property state.
TurboTax never knows about offsets to refunds and does not receive any information about them. The IRS sends a letter AFTER they seize the refund.

NOTE: You can contact the IRS Treasury Offset Program Call Center at 1-800-304-3107 to ask if they have an offset for you on file. TurboTax would not have that information.
