I am obtaining tfestimate from time-series data, given the form , where Vin and Vout correspond to vectors containing input and output voltages, respectively.

I have used tfestimate in the form of [EstH, EstF] = tfestimate(x,y,[],[],[],10);.. This generated a 513 x 1 matrix for EstH in the form of a+bi and a 513 x 1 matrix for EstF with 'double' as the datatype. I would now like to obtain a second order transfer function, given the resultant. I am wondering what would be the best aproach? I would like obtain the function and intend to plot it ontop of a previously generated bode plot, for verification purposes.

As always, my pleasure!
Since you were using Signal Processing Toolbox functions, I was not certain that you had the System Identification Toolbox, so I just suggested it as an option.
