You may not be applying online as you have to apply using the method needed to apply in the country you are applying from. If possible apply in Turkey if possible as Malaysia is not considered a good place to apply fot Thai Visas .
One thing to consider is the 50,000B International Transfer Limit.
The limit of 50,000 Baht in international transfers is ONLY for people who use WISE to transfer the money and ONLY for people using a bank OTHER THAN Bangkok Bank, Siam Commercial Bank or Kasikorn Bank. Consider these three banks first (I have Kasikorn).
No, the standard time is when you have 30 days remaining although a few offices allow extensions 45 days out but Jomtien and Samui will not extend until the last 7 days
