I can understand. nothing is clear. but dont worry. this group has many people who can give process tips.
DO you have a GD certificate from a Psychiatrist? That an a notorized affidivat stating your new gender and new name.
Use these to upload to GOVT SMILE portal to apply for TG card. This is very important for every document update in the future . It can take 2 -3 months with regular followup.
In your adhaar card, you can change gender directly to female for the first update.
But for name change they ask for gazzette publication even though TG card is valid as per law.
Once you have adhaar card and TG certificate and card in place, life will be easier.
