What is the pH of a solution containing both 0.954 M formic acid (HCO2H, Ka = 1.8x10-4) and 1.260 M phenol (HC6H5O, Ka = 1.6x10-10)?

The pH of the solution will be determined essentially by the formic acid because it is the stronger of the two. I would do an ICE chart for HCOOH and solve for H^+, then convert to pH.
