This is my first time filling alone, i know nothing about tax filling. I only have one T4 document to file related to the job i did for 2023, what filling option is best?

I can afford the option where an expert does it for me, i just want to know if it's worth it or should i do it partially/fully by myself because it's only one single T4 for the whole year that needs to be filed. Thank you very much for your help!
