No one has access to your tax return. No one can change anything on it for you. If you want to put the Roman numerals for "the second" in My Info, you hit the shift key, and use the letter "i". The appearance of the numerals -- II --- is a result of the font used by the software. No need to stress over it.
I might also mention that often, if you are the "second" person with the same name, you can use "Jr." instead of II, and worry about using III for the "third" person with the same name.
The IRS is matching your Social Security number.
