TSA Precheck Questions regarding gender currently only allow M or F. But apparently your choice. Either one is OK. But they plan to provide more options in the near future.
Why do they even ask if it does not matter?

The Questions

Am I required to select the gender that matches the gender on my identity documentation?

You can now select your preferred gender, even if the gender you select does not match the gender on your supporting documentation (such as birth certificate, passport, or state ID). You can select “M” or “F” which are the gender options currently available.

Is medical certification required to change the gender options for TSA PreCheck®?

Medical certification is not required to change the gender options on your TSA PreCheck® application. If you are a member of the TSA PreCheck® Application Program, you may call (855) 347-8371 weekdays, between 8 a.m. and 10 p.m. ET, to request a change of your gender options in your records. You may also submit your inquiry online. Please note, updating your gender is not required to receive TSA PreCheck® screening. You will receive TSA PreCheck® screening even if your current gender differs from the gender you provided when you enrolled in TSA PreCheck®.

What does it mean that I can self-select my preferred gender during the TSA PreCheck® application process?

You can select the gender you would like in your TSA PreCheck® record by simply checking “M” or “F”. Medical certification or a physician’s letter is not required when enrolling with a gender that does not match the gender on your identification documents.

Do I need to have the gender on my birth certificate, passport and/or driver’s license changed before I can get it changed on my TSA PreCheck® application?

No, the gender on your identification documents does not need to match the gender you select on your TSA PreCheck® Application.

If I identify as neither male “M” or female “F” or I have identity documentation in a non-binary gender, can I apply with a non-binary gender options or no gender options?

You can still apply for TSA PreCheck® but you must select “M” or “F” which are the gender options currently available. TSA is in the process of adding a third gender option for non-binary, intersex, and gender non-conforming individuals but cannot provide an exact timeline for when we will begin offering a third gender options.
