Hi aspirant,

Yes apply for mbbs seats in Gujarat and Karnataka through all India counselling even if you are from Maharashtra state. However through to all India counselling only 15% of the total seats are filled for a particular course in a state, you will have much better chances if you go through the state quota. Now every State authority has define some criteria for calling a candidate eligible for state quota reservation the details for which can be seen at https://medicine.careers360.com/articles/neet-domicile-criteria

Now talking counselling forms, MCC is yet to start the neet counselling for the 2021 session and the state counselling which will be conducted by respective state authorities would start only after that. You can find the complete details about the counselling at https://medicine.careers360.com/articles/neet-counselling

Hope it helps!!
