Aplication fees spouse and 2 child's

[Aiss]

Hello,
I paid the application fees online and I am still thinking if I did it right or not. Could someone confirm me or correct me please.
I paid for my wife and to dependent child ( one over 22 and one under 22 ) $1250. I am confused about the sponsorship application ,I paid $75 and I have the filing that is not right. I tried to call the immigration office but no one picked up the phone.
If I am wrong ,how I will pay the outstanding amount?
Thank you .

Yes, you paid the right amount for the application fees. Later you will be asked to pay the right of permanent resident fees if PR is granted.
