Why are the residuals of the other two equations not zero?s

Impossible to find the steady state

In that case, you need to find out why your entered equations and your manually computed steady state do not match. At least one of the two must still be wrong. The resid-command tells you which equations are not solved, given the values you provide. Focus on those. Initial values are the starting values for a numerical solver that tries to find the steady state. Steady state values are analytical values that solve the equations without running a solver.
