This is helpful to know, but I did want to clarify that I have 2 first names, a middle name then 1 last name. I just wanted to make sure that if I do put my middle name as part of my last name, it isn't wrong because I realize that my official last year's tax return when I download it shows my last name including my middle name and then in the box where it says first name and middle initial, it just says my first name. I just want to be cautious that I am filling it out correctly, but if I can do the same thing I did last year then that's okay.
