If it’s only one TextBox:

TextBox tb = (TextBox)pchStep4Adult.FindControl("tb1");

If your example was simplified and you actually have multiple TextBoxes, you could loop the PlaceHolder’s ControlCollection to get all TextBoxes.

foreach (Control ctrl in pchStep4Adult.Controls){
    TextBox txt = (TextBox)ctrl;
}
