Wrong minor head for challan 280

Dear Experts,

 Need you kind help in this matter.
  I got intimation to demand Rs. 1300 as tax payable.

 I e-filled the challan 280, with Minor Head as 300 [Self Assesment].

Now,
      My question is this correct ?
     or I should have selected Minor Head as 400 [Regular Assesment] ?
     Will it really impact as the required money is already submitted to IT detpartment ?

 

Regards
