Do you as a parent have to turn over financial info,and or personal in to a grandparent

The first question I would ask is whether or not the grandparent even has grounds to seek access to the child. "In Texas, a court can authorize grandparent visitation of a grandchild if visitation is in the child's best interest, and one of the following circumstances exists: The parents divorced; ... A court-order terminated the parent-child relationship; or. The child has lived with the grandparent for at least six months."  (OAG website) If you are not represented by counsel, then I would recommend you hire an attorney. This area of family law can be extremely tricky and you may lose some important parental rights if you are not properly represented. Assuming she has grounds to seek grandparent's rights, her attorney would have to make this request via formal discovery (unless local rules requires automatic disclosure of certain information) and the request would have to be relevant to the pleadings.
